Question

all 198 books rebecca labeled were priced at 1.75 per book. By 4:00 pm, all but 80 of those books had been sold. What was the total amount of money collected from the sale of these books

Answer 1

so alll BUT 80 were sold
198=80+sold
subtract 80 from both sides
118=sold

so if 1.75 per book
amount collected=number of books times cost per books
amount collected=118 times 1.75
amount collected=206.5

the amount colected is $206.50
