Step

Find the amount in sales for the month of February Employee #1

Let

x---------> the dollar amount in sales for the month of February

we know that

$2,000+\frac{3}{100} *x = 4.7*1,000 \\\\ 0.03*x=4,700-2,000\\\\ x=\frac{2,700}{0.03}$

$x=\$90,000$

the dollar amount in sales for the month of February of the Employee #1 is $x=\$90,000$

Step

Find the amount in sales for the month of February Employee #2

Let

x---------> the dollar amount in sales for the month of February

we know that

$\frac{7}{100} *x = 4.9*1,000 \\\\ 0.07*x=4,900\\\\ x=\frac{4,900}{0.07}$

$x=\$70,000$

the dollar amount in sales for the month of February of the Employee #2 is $x=\$70,000$

Step

Find the amount in sales for the month of February Employee #3

Let

x1---------> the dollar amount in sales for the month of February on the first $\$40,000$

x2---------> the dollar amount in sales for the month of February on anything over $\$40,000$

on the first $\$40,000$

we know that

$5\%$ of $\$40,000$ is equal to $\$2,000$

earning in February is equal to $\$4,400$

$\frac{5}{100} *x1 = 2,000 \\\\ 0.05*x1=2,000\\\\ x1=\frac{2,000}{0.05}$

$x1=\$40,000$

$\frac{8}{100} *x2 = (4,400-2,000) \\\\ 0.08*x2=2,400\\\\ x2=\frac{2,400}{0.08}$

$x2=\$30,000$

$x1+x2=\$40,000+\$30,000=\$70,000$

the dollar amount in sales for the month of February of the Employee #3 is $\$70,000$

therefore

the answer is the option

a. Employee #1
