Tim mows neighborhood lawns for extra money. Suppose that he would be willing to mow one lawn for ​$13

​,
a second lawn for ​$17
​,
and a third lawn for ​$24
.
Also suppose that three neighbors are interested in having their lawns mowed. Mrs. Jones would be willing to pay ​$30

to have her lawn​ mowed, Mr. Wilson would be willing to pay ​$26
​,
and Ms. Smith would be willing to pay ​$24
.

Answer 1

If Tim mows the first lawn for $13, then mows another for $17, the next for $24. Then he mows another three lawns for his neighbors which is priced as follows:

Mrs. Jones will pay $30, Mr. Wilson will pay $26, Ms. Smith will pay $24.

The total earnings of Tim will be:

$13 + $17 + $24 + $30 + $26 + $24 = $134
