Store A charges $10.00 for a pack of hotdogs and $8.00 for a pack of hotdog buns. Store B charges $11.00 for a pack of hotdogs and $7.50 for a
pack of hotdog buns.
Suppose you buy x packs of hotdogs and y packs of hotdog buns at both
stores. You end up spend $80.00 at store A and $81.50 at store B.
Which system of equations represents the total amount of money you
spent on hotdogs and hotdog buns at each store?

the answer is 200

step-by-step explanation:

the way the question is worded, it seems to imply the $264 interest is simple interest, not compound interest.

the simple interest for 2 years is $264; the simple interest for 1 year is $132.

$132 interest on a $600 investment means an interest rate of (132/600)*100 = 22%.

the value of $200 at 22% interest compounded annually for three years is

200%281.22%29%5e3

the amount of interest is that value, minus the original $200.
