Marco needs $57 to buy new basketball shoes. if marco earns $3 per day working and already has $12 saved, which equation shows how many days marco must work before he can afford the shoes?

Let x represent number of days.

We have been given that Marco earns $3 per day working. So amount earned in x days would be .

We are also told that Marco already has $12 saved, so total amount saved by Marco in x days would be .

Now we will equate total amount saved by Marco in x days with 57 as Marco needs to save $57 to buy new shoes.

Therefore, the equation shows the number of days (x) that Marco must work before he can afford the shoes.

$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)

my answer is$ 12

step-by-step explanation:
