Arnold buys 3  35  pounds of green grapes for $1.85 per pound. he buys 3  35  pounds of red grapes for $2.30 per pound. which expression can be used to determine the total cost, in dollars, of the grapes arnold buys? a)3.6(1.85 + 2.30)b)3.6 • 1.85 • 2.30c)(3.6 + 3.6)(1.85 + 2.30)d)(3.6 • 3.6) + (1.85 • 2.30)

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.
