Ron's car has a 12-gallon gas tank. If gas costs $1.45 per a gallon, how much will it cost to fill the tank?

12 * 1.45 = ?

To find out how much it will cost to fill Ron's car's gas tank, we can multiply the number of gallons in the tank by the cost per gallon.

Given that the car has a 12-gallon gas tank and gas costs $1.45 per gallon, we can calculate the cost as follows:

Cost to fill the tank = Number of gallons in the tank x Cost per gallon

Cost to fill the tank = 12 gallons x $1.45/gallon

Using simple multiplication, we find:

Cost to fill the tank = $17.40

Therefore, it will cost $17.40 to fill Ron's car's gas tank.
