If prizes for a carnival are priced at 5 for 80 cents. how much would 250 prices cost?

The answer is 4,000 is the cost

Ratio and proprtion

number of prized to price is 5 to 80 or 5/80 which can be simplified to 1/16

1 price to 16 cents equals 250 prizes to x cents

1/16=250/x

times both sides by 16x aka cross multiply

x=250*16

x=4000 cents or $40 for 250 prizes
