Question

Eloise makes & sells screen print t-shirts. She needs to buy some supplies. Paint costs $89.23 & a new screen costs $23.25. She saves 28.9% if she uses her store membership card. How much will Eloise save?

Answer 1

(89.23 + 23.25) * 0.289 = ?

Answer 2

I got 32.50672? Is that correct? My calculator is bad.. would the formula be Prt?

Answer 3

Your answer is correct. However, you need to round it to the nearest hundredth because you're saving dollars and cents.

PRT means Prinicipal times Rate times Time. That is the way to figure interest.

Answer 4

We haven't learnt that yet. I only know the basics of rounding to the nearest tenth but not hundreds yet. Would it be 32.6? Just one up?
What formula did you use?

Answer 5

Think about money. If something costs a dollar and 99 cents, we write it as $1.99.

So you need two decimal places when you round to the nearest hundredth.

32.50672 = $32.51

Answer 6

Okay i'm just taking the hundredths place not the tenths. Thank you. Can you help me with one more problem that i've been stuck on? Its about interest rates and its confusing me

Answer 7

Sure, I'll be glad to help you with interest rates.

Answer 8

i think its about interest rates because it mentioned interest
sophie owns a restaurant. She has an overdraft line of credit. Each overdraft transaction costs $43.20, plus interest at 54%/yr. On wednesday, Sophie had 9 overdraft transactions for $562. She paid back the money in 15 days. How much are the transaction fees?

Answer 9

Do you mean 54% per year? That's usurious.

Answer 10

Yes i forgot to put it there but since its interest it would be 0.54 ? right

Answer 11

Please go back and check your problem. I doubt if it's 0.54%.

Answer 12

yes it said "plus interest at 54%/yr" is that impossible?

Answer 13

Are you sure it isn't 5.4% a year?

Answer 14

No but it might be a typo i think it is 5.4 then
