INCREASING/?

@jim_thompson5910 ???can you help me? please

i really need help,guyss

Your increasing because when you multiply 2 positive numbers you increase

|dw:1437183261078:dw|

You increased when multiplying 2x2. Mai name is the answar

i dont know, :(

f(x) = a(r)^x
f(x) = 72(1.25)^x
r = ?

90?

|dw:1437183987216:dw|

|dw:1437184021635:dw|

look at the underlined parts
can you tell me what r = ?

1.25?

increasing?

|dw:1437184167487:dw|

|dw:1437184385353:dw|

not quite, perhaps we work it out a bit differently
1.25 = 1 + __
fill in the blank

this its what i get 1.25

not quite
what number do I have to add to 1 to get 1.25?

|dw:1437184481903:dw|

|dw:1437184579597:dw|

wat

1.25 - 1 = ?

0.25?

so we're finished with part A, ready to move to part B?

so wait the answer for part A? its

0.25 (which is also equal to 25%) represents the percent increase per year?

please read what part A is asking and review what we have done so far

"Part A: is the price of product A increasing or decreasing and by what percentage per year?"

increasing? right?

right, and what percentage?

25%? right?

right
now are you ready to move to part B?

yes

its 2?

o no wait

o yes its 2? right?

|dw:1437185687149:dw|
try one more time

its 1.32?

oh, whoops, typo on my part
|dw:1437185910222:dw|

can you try again, using 65 instead of 64?

65/64? thats what u say?

that's not what I meant, please look at this diagram
|dw:1437186028756:dw|

1.3? :/

its 0.3?

yes! so, our increase is 0.3, which is the same as 30%

its that a question?

we need it to solve the last question

we found the percent increase for product A and product B, now tell me which one is bigger

right

so whats nexts?

which product had the bigger increase? A or B?

A?

please read over what we did carefully...

also, please read the problem again

O sorry my bad

its B SORRY

right

SO we done?

yes

for make sure i writte correct the answer its:

Part A: the price of product is increasing 25%Part
Part B: 1.3

i writte correct

... please read what part B is asking

"Part B: Which product recorded a greater percent change in price over the previous year?"

B? 0.3? :/

it's asking which product (product A or product B) had the greater percent change

ITS product B? RIGHT

right

SO thats the answer for part B

right
