Ali can bake 105 cookies in 3 hours. At that rate, how many cookies can she bake in 5 hours?

so first you find out how many she can bake in 1 hour so you divide 105 and 3 which is 35

so since she bakes 35 cookies and hour you multiply 35 by how many hours she cooks

so 35 x 3 =105                    35 x 5=175

Ali cooks 175 cookies in 5 hours

$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)
