A is 45 b is 90 and c if 90
So first you multiply 2 and 4x to get 8x. Then you multiply 2 and 5 to get 10. So the problem will look like:
8x+10=90
Then you subtract 10 on both sides of the problem to get:
8x=80
And then divide 8 on both sides to get
x=10
For shop smart, the price is 48 packs for 9 dollars so you would divide
9 ÷ 48 to find the price for dollars per can which is 19 cents per can
for super save it's saying 48 packs for 10 dollars so divide
10 ÷ 48 and that is 21 cents per can
for price buster it's saying 36 packs for 9 dollars so you would divide
9 ÷ 36 which is 25 cents per can
so Mei Pilar and David should purchase the cans at shop smart since it's cheaper
