To find out how much it cost Mrs. Martinez to put in 14 gallons of gas at a rate of $3.62 per gallon, you can multiply the cost per gallon by the number of gallons.
Cost = Price per gallon × Number of gallons
Cost = $3.62 × 14
Now, let's do the multiplication:
Cost = $3.62 × 14 = $50.68
Therefore, the answer is:
A. $50.68
