Dominic works on the weekends and on vacations from school mowing lawns in his neighborhood. For every lawn he mows, he charges
Ivahew [28]

Answer:

20\ lawns = \$240

9 \ lawns = \$108

<em>See Attachment for Graph</em>

<em></em>

Step-by-step explanation:

Given

1\ lawn = \$12

Solving (a): Number of lawns in $240

1\ lawn = \$12

Multiply both sides by 20

20 * 1\ lawn = \$12 * 20

20\ lawns = \$240

Solving (b): Cost of mowing 9 lawns

1\ lawn = \$12

Multiply both sides by 9

9 * 1\ lawn = \$12 * 9

9 \ lawns = \$108

To create a graph, we need to generate a formula;

If

1\ lawn = \$12

2\ lawn = \$24

3\ lawns = \$36

x\ lawns = \$12x

So:

<em>The graph formula is</em>

y = 12x
