Answer 1

Answer:

a.) 7x-15=20

b.) 35-15

c.) he bought 5 bags

Answer 2

Answer:

Let the entire purchase amount be the number of bags he bought, B, times the price per bag

So B*8 = the entire purchase price

From this ...he subtracts 10 and pays 30

So we have this

B*8 - 10 = 30 add 10 to both sides

B*8 = 40 divide both sides by 8

B = 5 bags
