Answer 1

Explanation:

Answer 2

Option B) (1, 16.5)

Explanation:

Let

x ----> the number of lawns mowed

y ----> the amount earned in dollars

we know that

To find out the unit rate divide the total amount earned by the number of lawns mowed

so

`(82.50)/(5)=\$16.50\ per\ lawn`

That means ---> The amount earned by mowed 1 lawn is $16,50

therefore

The ordered pair is (1,16.50)
