A Salesperson receives a weekly salary of $100 plus a 5.5% commission on sales. Her salary last week was $1090. What were her sales that week?
$1,090 - 100 = $990.
This is her commission.
Let s = Sales.
So 0.055s = $990
Divide each side by 0.055.
s = $18,000
$1,090 - 100 = $990.
This is her commission.
Let s = Sales.
So 0.055s = $990
Divide each side by 0.055.
s = $18,000
