If eight trash bags last for thirty days then twenty eight trash bags will last for how many days

105 days

Step-by-step explanation:

30 divided by 8 to get the rate which equals 3.75

28*3.75= 105 days

$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)

its 50 miles away from the starting point
