Answer:
509 gallons as 815 gallons divided by 32 = 25.468 and we multiply by 20 to get 509.375 where we round down at 509 to find full gallon, anything less (via decimal) is not a full gallon.
Step-by-step explanation:
Answer:
39.15 or 39 gallons
Step-by-step explanation:
1. create an equation
815= 32+20x
2. get x by itself
783=20x
3. divide 20 to both sides of the equal sign
39.15=x
4. So Mike can buy 39.15 or 39 gallons of gas for 20$
