Answer and explanation:
1. It asks for the total expenses for the month of March. So, let's add all of the March expenses up.
1,600 + 2,100 + 850 + 480 + 2,800 = $7,830 (which is the answer)
2. It asks what the highest expense for wages are. That would be $5,080. Out of all of the times that the wages have been paid, in April, it was the highest, at $5,080. So, $5,080 is the answer.
3. It asks how many items cost less than $1,000 in April. The only thing that cost less than $1,000 in April was the water because it only cost $370. So, the answer would be 1.
Hope this helps!
