Angela earns a base salary of $842 each week and a 4% commission on products she sells. Her earnings last week were $879.60. What was the value of the products she sold?

$937.50

0.04 x 937.50 = 37.50

Step-by-step explanation:

Percentage of  4% would only multiply $4 per 100, $40 per 1000

and as this is under 1000 we only have to multiply 1.4 x 37.50

then multiply that answer by 1.4 again and get 62.5 then subtract from a 1000 = 937.50

0.04 x  937.50  =  37.50
