Answer:
112=4.5p+40
16
Step-by-step explanation:
40+4.50x+112
16 shoes daily to make his goal
to find how much shoes he would have to sell take away 40 from both sides of the equation which would leave you with 4.50x=72 next divide 4.50 out of both sides of the equation x=16 so he would have to sell 16 pairs of shoes a day to meet his goal
x=2
16/15
2p + 3d = 17
1p + 2d = 10
