Answer: $15.78
Step-by-step explanation:
Since 748 gallons = 100 cubic feet
4000 gallons will be equal to:
= 4000/748 × 100
= 5.3475936 × 100
= 534.75936 cubic feet
Since they pay $2.95 per 100 cubic feet of water, the cost for the family's water bill per month will then be:
= $2.95 × 5.3475936
= $15.78
