Question

You have saved $40 for a video game and your parents will contribute some money. They said they will give you $1 for every $4 you save. How much have they contributed

Answer 1

They contributed $8

Explanation:

Given

`Savings = \$40`

Proportion of savings:
`Parent = \$1`
`You = \$4`

Required

Determine your parent contribution

From the question, we understand that, they contribute $1 when you save $1.

This means that the unit savings is:

`Unit = \$4 + \$1`

`Unit = \$5`

The parent contribution is then calculated as:

`(Parent\ Proportion)/(Unit\ Savings) * Total\ Savings`

`= (\$1)/(\$5) * \$40`

`= (1)/(5) * \$40`

`= (1* \$40)/(5)`

`= (\$40)/(5)`

`= \$8`

Hence, they have contributed $8
