Question

8. A paint store has 35 gallons of paint in

storage, 2/5
of which are for outdoor use.
The others are for indoor use. If each gallon
costs $22, what is the total cost of the
indoor paint in storage?​

Answer 1

Total cost of the indoor paint in storage = $462

Explanation:

Total gallons of paint the store has = 35

Fraction of paints for outdoor use =
`(2)/(5)`

Number of gallons for outdoor use can be found out by finding
`(2)/(5)` of total gallons of pain which is 35.

So, number of gallons for outdoor use =
`(2)/(5)* 35`

⇒
`(70)/(5)`

⇒
`14` gallons

The remaining gallons are for indoor use.

Number of gallons for indoor use =
`35-14=21` gallons

Cost per gallon of paint = $22.

Total cost of indoor paint in storage =
`Unit\ cost* Total\ gallons\ of\ indoor\ paint`

⇒
`22* 21`

⇒
`\$462` (Answer)
