Question

Hector spent $ 17 for a tube of paint and 5 brushes. The tube of paint cost $8. Which equation can be used to find b, the cost of each brush?

Answer 1

if b is a brush than 5 brushes are 5b
all the items cost 17,so
17=8+5b

Answer 2

1 tub paint=8     5 brush=?
8+5b=17
5b=17-8
5b=9
b=9/5   
b=1.8  ($1.80 each brush)
