Al earns $500 a week selling shoes. He also earns 8% commission on all of his shoe sales. Last week, he sold $1,540 worth of shoes. How much money did Al earn last week?

Respuesta :

He earned $623.20.

He earns 8% commission on his sales; 8% = 8/100 = 0.08

He sold $1540 in shoes:
0.08(1540) = 123.20

Add to this the $500 he makes weekly:
123.20+500 = $623.20
