Alexa is deciding where to buy a new camera. each store offers a 1-year loan for $450 but with different interest rates and fees. which is the best way for alexa to choose the $450 loan that will cost her the least?

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.

x/3-10=8

x/3=18

x=48
