Question
Solve the inequality and answer the question.
4 + 0.15x < 20 + 0.05.x
This is the inequality that
models the verbal conditions.
4 + 0.15x – 0.05x < 20 + 0.05x – 0.05x
Subtract 0.05x from both sides.
4 + 0.1x < 20
Simplify.
4 + 0.1x
4 < 20 – 4
Subtract 4 from both sides.
0.1x < 16
Simplify.
0.1x
16
Divide both sides by 0.1.
0.1
0.1
x < 160
Simplify.
Thus, driving fewer than 160 miles per day makes Acme the better deal.
