Maria works as a florist and worked 15 hours last week and earned $112.50. At that rate, how much will she earn if she works for 10 hours? * $73 $75 $55 $78

Rearranging the options we have;

a. $73

b. $75

c. $55

d. $78

From which the correct option is;

b. $ 75.

Step-by-step explanation:

To solve the question, we note that

Number of hours worked last week by Maria = 15 Hours

Amount earned by Maria for work last week = $ 112.50

Therefore by finding the hourly rate, that is how much Maria is being paid per hour, we get

15 Hours = $ 112.50

Therefore dividing both sides of the equation by 15 we get

15 Hours/15 = $ 112.50/15 which gives

1 Hour = $ 7.50

To find out  how much will she earn if she works for 10 hours, we have

1 Hour = $ 7.50

Therefore multiplying both sides of the equation by 10 we have,

1 Hour × 10 = $ 7.50 × 10

10 hours = $ 75.00

That is she would earn $ 75.00 in 10 hours.

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.
