Trey made $324 for 18 hours of work. At the same rate, how many hours would he have to work to make $216?

12 hours

Step-by-step explanation:

Let x be the amount of money he makes in 1 hour

324=18x

x=18

So, we know that 18 time the number of hours will be 216

Let y be the number of hours

18y=216

y=12

12 Hrs

Step-by-step explanation:

You must first divide 324 by 18 to find how much he makes per hour and then divided that by 216

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.
