Deshaun works mowing lawns and babysitting. He eams $8.50 an hour for mowing and $7.30 an hour for babysitting. How much will he earn for 6 hours of
mowing and 5 hours of babysitting?

$87.50

Step-by-step explanation: Lets write an expression to represent this situation.

(8.50 x 6) + (7.30 x 5)

Next solve inside the parentheses first. 8.50 x 6 = 51 and 7.30 x 5 = 36.50

Now we add

51 + 36.50 = 87.50

So in total, Deshaun will earn $87.50

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.
