8. example 1 - calculating hourly wages
joe works at the local hardware store. he is earning $7.75 per hour. if this
upcoming week he works a total of 36 hours, what will his gross earnings be for
the week?

279.00

Step-by-step explanation:

7.75x36

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.

80%
