Answer:
$6.75
Step-by-step explanation:
find the cost of each individual bag
11.25 ÷ 5 = 2.25
multiply that by the amount of bags needed
2.25 × 3 = 6.75
You should ask your parent/guardian
or teacher if needed! Merry Christmas!
3x-4y=10
-20-x+2y=10 then -30+2y=x now plug this in the other equation:
3(-30+2y)-4y=10
-90+6y-4y=10
2y=100
y=50
