Question

Last month, Belinda worked 160 hours at a rate of $10.00 per hour. If her employer retains 9% of her gross salary, is $1,500 a reasonable estimate of her net salary?

Answer 1

We have been given that last month, Belinda worked 160 hours at a rate of $10.00 per hour.

Let us find amount earned by Belinda last month as:

`\text{Amount earned in 160 hours}=\$10* 160`

`\text{Amount earned in 160 hours}=\$1600`

We are also told that Belinda's employer retains 9% of her gross salary. This means that Belinda's net income will be 91% of $1600.
`(100\%-9\%=91\%)`.

`\text{Belinda's net income would be}=\$1600 * (91)/(100)`

`\text{Belinda's net income would be}=\$16* 91`

`\text{Belinda's net income would be}=\$1456`

Upon rounding $1456 to nearest hundred, we will get:

`\text{Belinda's net income would be}\approx \$1500`

Therefore, $1500 is a reasonable estimate of her net salary.
