Question

4.) Laura works in a furniture store. She earns $160 a week plus 6% of all sales over

$2,000. One week in January, Laura's total sales were $9,400. What were Laura's
earnings for that week?

Answer 1

$724

Explanation:

You can do this one of two ways. The first way is to set up an equation.

160+0.06(9400)

160+564

724

Or you can use proportions.

`(x)/(9400)` =
`(6)/(100)`

Cross multiply.

100x=56400

Divide by 100 on both sides.

x=564

Add 160.

564+160=724.

Answer 2

$724

Explanation:

We know she makes the 6% of the 9,400, so we need to find how much that is.

To do this we calculate the following equation: 9,400 * 0.06

When we solve this, we get 564. From there we add her weekly salary (160) and get 724.
