Harriet earns the same amount of money each day. Her gross pay at the end of 7 workdays is 35h+56 dollars. Which expression repr
AnnyKZ [126]

Answer:

Gross pay for each day is 5h + 8 dollars.

Step-by-step explanation:

Given:

Number of days = 7

Gross pay for 7 day = 35h+56 dollars.

We need to find the gross pay for each day

Also given Harriet earns the same amount of money each day.

Hence

For 7 days = 35h + 56 dollars

for 1 day = gross pay for each day.

By using Unitary method we get;

Gross pay for each day = \frac{35h + 56}{7} = \frac{35h}{7}+\frac{56}{7}= 5h+8

Hence gross pay for each day is 5h + 8.
