step 2

Convert to pints

48\ l=48*1.75=84\ pints

step 3

Convert to gallons

84\ pints=84/8=10.5\ gal

Grocery market:

4 boxes for $10

Unit price = cost / quantity

= $10 / 4 boxes

= $2.50 per box

Food market:

Price per box = $2.25

The better value option based on price is food market because it cost less to buy a box of cereal than grocery mart
