Answer:

D) $40

Explanation:

We need to find the DIFFERENCE between Susan's and Jim's lawn care business in the amounts they charge for 10 hours at work.

Solution:

First we will find the hourly charges of lawn care for both.

Given:

From the table of Jim we can see that

Charges of Jim for 1 hour = $20

So for 10 hour = Charges of Jim for 10 hour.

By using Unitary method we get;

Charges of Jim for 10 hour =
`10* 20 =\$200`

Now From table of Susan we can see that;

for 2 hours = $48

So for 1 hour = Charges of Susan for 1 hour.

By Using Unitary method we get;

Charges of Susan for 1 hour =
`(48)/(2)= \$24`

Now we know that;

Charges of Susan for 1 hour = $24

So for 10 hour = Charges of Susan for 10 hour

again by using Unitary method we get;

Charges of Susan for 10 hour =
`24*10 =\$240`

Now we need to find the difference between their charges.

Difference can be calculated by subtracting Charges of Jim for 10 hour from Charges of Susan for 10 hour.

framing in equation form we get;

Difference =
`\$240-\$200=\$40`

Hence The difference in the charges for 10 hour of work is $40.
