Answer:
35.7 gallons
Step-by-step explanation:
Given that:
Distance traveled = 700 miles
Gasoline used = 25 gallons
The gallons of gasoline used are directly proportional to the number of miles traveled.
To find the gallons of gasoline to be used after driving 1000 miles, we can use the unitary method in which we first of all find, how much gallons of gasoline would be used for 1 mile and then multiply the value with 1000 to find the answer.
700 miles are traveled by gallons of gasoline = 25
1 mile is traveled by gallons of gasoline = [tex]\frac{25}{700}[/tex]
1000 miles are traveled by gallons of gasoline = [tex]\frac{25}{700}\times 1000 = \bold{35.7\ gallons}[/tex]
