Question

What is the slope the jelly junior high school color is made by mixng red paint with yellow paint. The ratio of the red to yellow is 3 to 5. How much red paint should be mixed with 20 oz of yellow

Answer 1

12 oz of red paint should be mixed.

Explanation:

Ratio in which red and white colors are mixed = 3 : 5

Let the total amount of paint prepared with red and white color = x oz

Amount of yellow paint used =
`(5)/(3+5)* x`

=
`(5x)/(8)` oz

Since, amount of yellow paint mixed = 20 oz

Therefore,
`(5x)/(8)=20`

`x=20* (8)/(5)`

`x=32` oz

Total amount of paint = 32 oz

Amount of red paint mixed = Total amount of paint - Amount of yellow paint mixed

= 32 - 20

= 12 oz

Therefore, 12 oz of red paint should be mixed.
