Tomas is preparing a grocery budget for his restaurant. He knows that he uses a 10-pound bag of onions in 3 days. A 10-pound bag
of onions costs $9.50. Which strategies can Tomas use to determine his budget for onions in a month with 30 days?
A.
Tomas can use the proportion for the ratios of days to cost, 39.5=30x, to solve for x, the budget needed for onions in 30 days.
B.
Tomas can determine the number of 10 pounds bags of onions needed by multiplying by 30 days, and then using that in a proportion for the ratios of price to pounds, 9.510=x300, to solve for x, the budget needed for onions in 30 days.
C.
Tomas can use addition to determine the price per pound of onions and the number of pounds of onions per day, and then multiply by 30:(9.510+103)30=x.
D.
Tomas can subtract by 3 to find the cost of onions per 1 day, and then multiply by 30 for the monthly cost:(9.5−3)30=x.
Tomas knows that he uses a 10-pound bag of onions in 3 days. A 10-pound bag of onions costs $9.50. Thus, a $9.50 bag lasts 3 days. We're interested in the onion cost for 30 days, so we multiply numerator and denominator of this rate by 30 days. We thus obtain:
$9.50 * 30 days
------------------------ = $95.00
3 days
Tomas must budget $95 for onions for each 30-day month.
