Question

You spend $20 total on paint and brushes. Paint cost $4 each and brushes cost $0.50 each. You buy twice as many brushes as paint. How many brushes and paint did you buy?

Answer 1

Answer:

Brushes= 8, Paint= 4

Step-by-step explanation:

Given: Total spending on paint and brush= $20

           Cost of each paint= $4

           Cost of each brush= $0.50.

Let´s assume the number of paint bought be "x"

∴ number of brushes bought is "2x".

Now, forming an equation to determine the number of paint and brushes bought.

⇒ $\ 4\times x+ \ 0.50\times 2x= \ 20$

⇒$4x+x= 20$

⇒$5x= 20$

Dividing both side by 5

⇒ $x= \frac{20}{5}$

∴ $x= 4\ unit$

Hence, number of paint bought is 4 units.

Next finding the number of brushes bought.

Number of brushes bought= $2\times 4$

∴ Number of brushes bought= $8\ units$

Hence, number of brushes bought is 8 units.
