Answer 1

i think so its B 82.50÷5=16.5

Answer 2

Option B.

Explanation:

Consider the below table attached with this question.

It is given that Cambridge has a job mowing lawns. He mowed 5 lawns last week and earned $82.50.

We need to find the coordinate pair that represents the unit rate for this situation.

Unit rate represent the value of dependent variable when the value of independent variable is 1.

In the given situation, dependent variable is earnings and independent variable is number of lawns.

5 lawns = $82.50

Divide both sides by 5.

1 lawns = $16.5

So, the unit rate rate is $16.5 and the required coordinates are (1,16.5).

Therefore, the correct option is B.
