Answer:
The total amount of gas Ms. Smith used on the trip is $25.
Explanation:
To solve this problem, we first must figure out how many gallons of gas Ms. Smith used on her trip. If she drove 700 miles and averaged 35 miles per gallon, if we divide 700 by 35 we can figure out how many gallons she used.
700/35 = 20
Thus, Ms. Smith used 20 gallons on her trip. Next, to figure out what the cost of the gasoline was, we must multiply the number of gallons (20) by the cost of gasoline per gallon ($1.25).
20 gallons * $1.25/gal = $25
Therefore, the cost of gasoline for the trip was $25.
Hope this helps!
