Answer 1

(a) Brandon bought 5 gallons of paint for $90.

Explanation:

Given

Parvati:

`8\ gallon \to \$144`

Required

Person with the same paint

First, calculate the unit cost of Parvati's paint

`Unit = (\$144)/(8\ gallon)`

`Unit = \$18/gallon`

To get the person with the same kind of paint, we simply calculate the unit price.

Whoever has the same unit price as
`Unit = \$18/gallon` have the same kind of paint

Brandon

`Amount = \$90`

`Size= 5\ gallons`

So:

`Unit = (Amount)/(Size)`

`Unit = (\$90)/(5\ gallons)`

`Unit = \$18/gallons`

Brandon has the same paint as Parvati because the unit prices are the same.
