1 pound = 16 ounce.
8 ounce = 0.5 pound
14 ounce = 0.875 pound.
Cost of blueberries per pound at Grocery store = [tex]2.80\times0.5=5.6[/tex] dollars.
Cost of blueberries per pound at farmer's market = [tex]\frac{4.20}{0.875} =4.8[/tex] dollars.
$5.6-$4.8=$0.8
Hence, at farmers market, blueberries cost $0.80 less for one pound of blueberries.
Answer:
A pound of blueberries from the farmer's market is cheaper than a pound of blueberries from the grocery store.
Explanation:
The grocery store charges $2.80 for an 8-oz package of blueberries. This is a unit cost of
2.8/8 = $0.35 per ounce.
This means a pound, 16 ounces, would cost 16(0.35) = $5.60.
The farmer's market charges $4.20 for 14 ounces. This is a unit cost of
4.20/14 = $0.30 per ounce.
This means a pound, 16 ounces, would cost 16(0.3) = $4.80. This is
5.60-4.80 = 0.80 cheaper than at the grocery store.
