Melissa paid $12.98 for a 6.35-kg bag of food. A few weeks later she paid 14.88 for a 7.03-kg bag at a different store find the unit price for each bag then state which is better buy based on the unit price round your answer to the nearest cent

first purchase is a better buy

Step-by-step explanation:

6.35 kg cost $12.98 = $2.04

7.03 kg cost $14.88 = $2.12

$53.50

step-by-step explanation:

you have to subtract the amount of money chuck earned ($72.50) by the cost of the gas for the mower ($11.25) and the new string for the trimmer he bought ($7.75).

72.50-11.25=61.25

and then subtract $61.25 by the second thing he bought (the new string for the trimmer)

61.25-7.75=53.5

so in total it's $53.50 (53 dollars and 50 cents)
