Which strategies can be used to solve this problem?
A new company sold 4,284 pairs of boots in its first year, 3,726 pairs in its second year, and 2,125 pairs in its third year. How many more pairs did the company sell in the second and third year together than in its first year?
Choose all answers that are correct.
A.
Work backward. Add the amount of pairs sold in the second and third year together. Then subtract this amount from the pairs sold in the first year (4,284).
B.
Draw a diagram.
Draw 3 circles and write the number of pairs sold for each year. Cross out the circle with 4,284 in it. Circle the other 2 circles and add up the amounts in the circles.
C.
Use logical reasoning.
Combine the number of pairs sold in the second and third years (3,726 + 2,125). Then subtract the pairs sold in the first year (4,284) from the sum.
D.
Translate into an equation.
(3,726 + 2,125) – 4,284 = p

@princess1990, what are your thoughts regarding this problem?

- anonymous

my answer for this one is c and d

- anonymous

am i right

- Hero

Why only c and d? What's wrong with A and B. Try explaining.

- anonymous

ok well...

- anonymous

ok let me think

- anonymous

because you have to have a greater amount to subtract a smaller amount from it, and the other one is saying that your subtracting a larger number from a smaller number. and the circle one isn't even doing any subtraction.

- anonymous

right

- Hero

We know that B is definitely not correct, but do you think you could explain to me the significant difference between A and C?

- anonymous

i did

- anonymous

i ont know how to explain itno other way

- Hero

Take a closer look and A and C first. Then describe to me the similarities and differences between them.

- anonymous

i am honestly dumb right now and i only know i came up with c and d

- Hero

Can you tell me what A is asking us to do?

- anonymous

they are telling us to work backwards

- Hero

And what does working backwards involve?

- anonymous

Work backward. Add the amount of pairs sold in the second and third year together. Then subtract this amount from the pairs sold in the first year (4,284).

- Hero

You copy and pasted that, but yes. Add the amount sold in the second and third year together, then subtract that amount from that which was sold in the first year. If we did that, would we get a different answer from the one we got for C?

- anonymous

so is it c and d and no i did not copy and paste dont know how to do that

- Hero

Here's what we'll do. Calculate the answer you got for C. Let me know what you get, then post it here.

- anonymous

can u tell me if i am right or am i wrong

- Hero

I will in a minute, but first calculate what you got for C.

- anonymous

i dont know that what i came up with it and what with the 3rd degree here i just need help

- Hero

How do you know that C and D are correct if you don't know how to compute the numerical answer?

- anonymous

i just know can u just tust me

- Hero

Do you have a calculator with you?

- anonymous

i do mental math in my head my mind is the caculation

- Hero

So then what is the numerical answer to the given problem?

- anonymous

just what do u need me to caculated and i will give u the aswer

- Hero

How many more pairs did the company sell in the second and third year together than in its first year?

- anonymous

add them toghether

- Hero

Perform this operation: (3,726 + 2,125) – 4,284

- anonymous

421,567

- Hero

How did you get that?

- anonymous

i did what u told me to do

- Hero

Let's try adding just 3,726 + 2,125 first. What do you get for that?

- anonymous

5,851

- Hero

Okay, great...

- anonymous

so what the next step u act like i am pure stupid

- Hero

Now what is
5,851 - 4,284

- anonymous

1,567

- Hero

Yes, that is the numerical answer to the question. So D is correct. We just have to figure out which of the other options A, B, and C would give us the same answer we got for D.

- anonymous

ok

- Hero

You said C would also give us the same answer. I agree with that, but now we need to figure out if A or B would give us the same answer or not.

- anonymous

the other one is C

- anonymous

so its C and D

- anonymous

ok well gonna tag u in agian o have another question for u to check

- Hero

Well, actually, C and D aren't the only correct answers.
