Question

Each week, Tina earns $x babysitting and receives $10 as her allowance. To find how much she will earn in total over 4 weeks, Tina calculates:x + 10 + x + 10 + x + 10 + x + 10. What is another way Tina can calculate how much she will earn in total over 4 weeks?

Answer 1

Instead of using x + 10 + x + 10 + x + 10 + x + 10, use a formula like this:

$10 allowance is given per week
$x babysitting is given per week
4 weeks total

4 weeks (babysitting money + allowance)
It works out to this:

4(x + 10)
Where x represents babysitting money
4 represents the weeks
10 represents allowance

4(x + 10)

Answer 2

`4(x+10)`

Explanation:

To find how much she will earn in total over 4 weeks, Tina calculates:x + 10 + x + 10 + x + 10 + x + 10.

Another Way

Each week, Tina earns $x babysitting and receives $10 as her allowance.

So, total earning for each week = x+10

So, total earning for 4 weeks =
`4(x+10)`

Hence The another way of calculating her earnings in 4 weeks is
`4(x+10)`
