The table shows Marco’s checking account

activity for the first week of June.
a. Marco wants his total deposits for the month of June
to exceed $1,500. Write and solve an inequality to find
how much more he needs to deposit to meet this goal.
b. Marco wants his total purchases for the month to be less than $450.
Write and solve an inequality to find how much more he can spend
and still meet this goal.
c. There are three weeks left in June. If Marco spends the same amount in
each of these weeks that he spent during the first week, will he meet his
goal of spending less than $450 for the entire month? Justify your answer.

Deposit – Paycheck $520.45
Purchase – Grocery Store $46.50
Purchase – Movie Theatre $24.00
Purchase – Water bill $22.82

I know for a that it has to do something with adding them all together, but my answer of 520.45+46.50+24+22.82 ≤ m m=total money

I feel this isn't correct.
