Ok, I'd start by changing 549.99 to 550$ A tad easier that way

ok

no

Alright, let me try a different tactic then...

First, multiply the member price, 550$ by 10%

5500

Did you hit percent?

10% is not the same as 10

Oh.

550

Drop one more zero. 55

How would I get that on a calculator?

Do you have a percent button? If not, you can also use .10 for 10%

that's 0.10 Not ten

No. I will try using the decimal. I got 55

Ok!

$605

You got it :)

That's right as well

:)

Do you understand why .10 is equal to 10%?

Ok, before I give you a hint, try to get the first. 1.04$

What do you mean?

Each item is marked up 30%, so there are four answers here

Remember on the last problem, you multiplied the original price by .1, for 30%, what would you use?

Division?

$3.33 is that the answer?

Yeah.

You need to use 30% in this, so what decimal would you use?

.30

Good. Now he's a little trick. 50% is .50, 85% is .85, and 100% is actually 1

Ok!

If you add your markup decimal (.30) to 1, you get 1.3 Right?

Where did the one come from?

$1.04, $7.23, $9.99 and $42.77 Multiply each by 1.3 on your calculator

oh ok!

1.34
9.40
12.99
55.60

Perfect!

Now let me go back and show you something

You have a 10% Markup here, so take that .10, and add it to 1, like we did just now

1.1

Right, now multiply that by 550. Seem familiar? :)

605

Yep, that trick works for every price mark up problem!

Wait! Please help me with the first one.

Sure, what do you need? Although I need to go kinda soon

Same prices as before? $1.04, $7.23, $9.99 and $42.77?

Yes.

You have helped me so much! Thank you so much!

You are very welcome. Good luck with your studies!
