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

Answer:

They contributed $8

Step-by-step 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:

$\frac{Parent\ Proportion}{Unit\ Savings} * Total\ Savings$

$= \frac{\ 1}{\ 5} * \ 40$

$= \frac{1}{5} * \ 40$

$= \frac{1* \ 40}{5}$

$= \frac{\ 40}{5}$

$= \ 8$

Hence, they have contributed $8
