The value in cents of 4 quarters and x dimes

100 + (10x) cents

Step-by-step explanation:

The value in cents of 4 quarters and x dimes.

1 quarter = $0.25 or 25 cents

4 quarter = 25 × 4 = 100 cents or $1.00

1 dime = $0.10 or 10 cents

x dimes = $0.10x or 10x cents

Hence the value of 4 quarters and x dimes in cents = 100+(10x) cents

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.

1/800 is the right answer
