Arnies car used 100 cups of gasoline during a drive. he paid $3.12 per gallon for gas. how much did the gas cost?

$19.5 because there is 16 cups per gallon and 100 divided by 16 = 6.2 x 3.12  = 19.5  
 hope i helped :)

Answer for 2: his profit would be $2.88 explanation: you have to first multiply 72 and 0.12 together to get $8.64 once you do that you know how much money the shopkeeper made from selling the candy bars individually. so you have to do 8.64-5.76=2.88 hope that ; )answer for 3: yeah i’m sorry i have no idea what number 3 is. i’m sorry i couldn’t with that.

Bis the correct answer
