Answer:

Natasha paid $6 per paintbrush

Step-by-step explanation:

Cost for paint brushes

we can make use of variables

p = paint

b = brushes

bought paintbrushes and paint for a total of $71. . The brushes cost $3.50 per brush and the paint cost $50

we can create an equation from the information

3.5b + 50p = 71

since 1 paint is bought

3.5 b + 50 (1) = 71

3.5b = 71 - 50

3.5b = 21

b = 21/3.5

b = 6

paintbrush costs $ 6
