The cost of 14 gallons of gas is $19.46.

a. How much gas could you buy with $8.70? Use equivalent ratios to solve.

b. How much would it cost to buy 9.5 gallons? Use equivalent ratios to solve.

a ) 14 : 19.46$ = x : 8.70$ x = 19.46 14 ∗ 8.70 ​ = 19.46 121.8 ​ x = 6.258 ​ b ) 14 : 19.46$ = 9.5 : x x = 14 19.46 ∗ 9.5 ​ = 14 184.87 ​ x = 13.205 ​

A. First develop your ratio: 14 x ​ = 19.46 8.70 ​ where x is the amount of gas needed.
Divide the amount charged for x amount of gas by 19.46, then multiply that amount by 14 to get the amount of gas bought: 14 6.26 ​ = 19.46 8.70 ​
B. Again, develop your ratio: 14 9.5 ​ = 19.46 x ​ and use the same procedure.
Divide 9.5 by 14, then multiply your answer by 19.46 to get: 14 9.5 ​ = 19.46 13.21 ​
