Answer:
he should buy 128 oz of milk for 6.49
Step-by-step explanation:
2.49 divided by 32 equals 7 cents unless your rounding which would be 8 cents
4.99 divided by 64 is 7 cents too 8 if rounding
6.49 divided buy 128 oz would equal 5 cents so it is the cheapest.
The width of the sidewalk would be 10ft.
Sorry if incorrect
.45 * 120 = 54
.072 * 54 = 3.888
54 + 3.888 = 57.888= $57.89
