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:
[tex]\text{Amount earned in 160 hours}=\$10\times 160[/tex]
[tex]\text{Amount earned in 160 hours}=\$1600[/tex]
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. [tex](100\%-9\%=91\%)[/tex].
[tex]\text{Belinda's net income would be}=\$1600 \times \frac{91}{100}[/tex]
[tex]\text{Belinda's net income would be}=\$16\times 91[/tex]
[tex]\text{Belinda's net income would be}=\$1456[/tex]
Upon rounding $1456 to nearest hundred, we will get:
[tex]\text{Belinda's net income would be}\approx \$1500[/tex]
Therefore, $1500 is a reasonable estimate of her net salary.
