Question

Kara spend $16 on tubes of paint and brushes for an art project. Each tube of paint costs $3 and each brush costs $ 0.50. Kara purchased twice as many brushes as tubes of paint. Find the number of tubes of paint she purchased.

Answer 1

Answer: There are 4 tubes of paint she purchased.

Explanation:

Since we have given that

Amount spend on tubes of paint and brushes for an art project = $16

Cost of each tube of paint = $3

Cost of each brush = $0.50

Let the price of tube of paint be 'x'.

Let the price of brush be '2x'.

So, According to question, it becomes,

`3x+0.50* 2x=16\\\\3x+x=16\\\\4x=16x\\\\x=(16)/(4)\\\\x=4`

Hence, there are 4 tubes of paint she purchased.
