Question

Gasoline costs $3.79 per gallon.

Write an inequality that can be used to determine how many gallons of fuel can be
purchased for under $20. Clearly indicate what the variable represents.


Solve the inequality in part a, and write your answer in a complete sentence

Answer 1

Where c is the cost and g is the number of gallons bought
C=3.79g
20=3.79g
20/3.89=5.277
You can’t spend more than $20 so
3.79x<_20
X<_20/3.79=5.28
X<_5.28
You cannot buy more than 5.28 gallons
