Natasha bought paintbrushes and paint for a total of $71 to paint a fence. The brushes cost $3.50 per brush and the paint cost $50. How much did each paint brush cost?

Natasha paid $4 per paintbrush

Natasha paid $17.50 per paintbrush

Natasha paid $6 per paintbrush

Natasha paid $21 per paintbrush

Step-by-step explanation:

Cost of paint brushes= Total cost - cost of paint

                                   = 71 - 50 = $21

No.ofpaint brushes =21/3.50 = 21*10/3.5*10

                                 = 210/35 = 6

Natasha paid $6 per paintbrush

Step-by-step explanation:

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

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47
