Answer:
Total sales = $3,027.272727
= $3,027.28 (to 2 decimal places )
Explanation:
Gross Pay = $678
Salary = $345
Let total sales = x
Earnings on sales = 11% of sales = 11% of x
Gross pay = Salary + 11% of Sales
$678 = $345 + (11% of x)
$678 = $345 + 11x/100
$678 = $345 + 0.11x
Subtract $345 from both sides
$678 - $345 = $345 - $345+ 0.11x
$333 = 0.11x
Divide both sides by the coefficient of x (i.e. 0.11)
$333/0.1`1 = 0.11x/0.11
$3,027.272727 = x
x = $3,027.28 (to 2 decimal places )
