Answer 1

32.50-18.50=14
he spent $14 on gas, but we want how many gallons, one gallon is 3.50
so 14/3.50=4
She put 4 gallons in the can

Answer 2

Option B. 4 gallons.

Explanation:

Luiza bought a gas can and put gas in the can.

Luiza spend total = $32.50

She spend for gas can = $18.50

Therefore, Cost of gas = 32.50 - 18.50 = $14.00

Cost of one gallon gas = $3.50

for $14.00 she can purchase gas =
`(14.00)/(3.50)` = 4 gallons

Luiza put 4 gallons of gas in the can.

On the given number line pictures Option 2 is correct, that is shows 4 gallons.
