Define a variable. Then write and solve an equation for each situation.

The Parker family drove a total of 180 miles on their road trip. This distance is 1.5 times the distance they drove on the first day. How many miles did the Parker family drive on the first day?

180 = 1.5d
180 / 1.5 = d
120 = d <== the Parker family drove 120 miles
=================
80% of the total questions = 16
0.80x = 16
x = 16 / 0.80
x = 20 <== there were 16 total questions on the quiz
