-10 + a = 6a - 7a
Rearrange the left hand side
a - 10 = 6a - 7a
Simplify 6a - 7a
a - 10 = -a
Add a on both sides
2a - 10 = 0
Add 10 on both sides
2a = 10
Divide by 2 on both sides
a = 5
You must find the unit cost in dollars per gallon for each purchase by dividing the cost by the number of gallons.
Graven: $55.20 for 15 gallons
$55.20/(15 gal) = $3.68/gal
Project: $72.80 for 20 gallons
$72.80/(20 gal) = $3.64/gal
Answer: Project paid less per gallon.
