Answer:

19 miles

Step-by-step explanation:

Let m represent the number of miles traveled. Then the delivery charge is ...

charge = $5.00 + $0.15·m

You want to find the value of m that makes the charge by $7.85, so you want the solution to ...

$7.85 = $5.00 +$0.15·m

$2.85 = $0.15·m . . . . . . . . . subtract $5 (this gives the mileage charge)

$2.85/$0.15 = m = 19 . . . . . divide by the coefficient of m

The number of miles traveled is 19.

Total 209 116 325

<h3>What is a two-way table?</h3>

A two way table is used to show the frequency of two categorical variables. Information are usually presented in rows and columns.

The 7th grade students that have no pets = 150 - 102 = 48
The 8th grade students that have pets = 175 - 68 = 107
Total students that have pets = 102 + 107 = 209
Total students that have no pets = 48 + 68 = 116
Total = 209 + 116 = 325
