Question

You have $120 to buy food trays for a super bowl party. The vegetable trays cost $20 each and the sandwich trays cost $30 each.

Answer 1

I'm assuming you need to find how many you can buy, which is 2 sandwich trays and 3 vegetable trays

Explanation:

120 - 30 = 90

90 - 30 = 60

Since 60 is the only even number you can use to subtract twenty from evenly, that's where you want to stop.

60 - 20 = 40

40 - 20 = 20

20 - 20 = 0

Answer 2

3 vegetable trays, 2 sandwich trays

Explanation:

I'm not quite sure what we're supposed to find, but if we were to find how many of each we can buy with $120 it would be 3 vegetable trays and 2 sandwich trays.

20 + 20 + 20 = $60

30 + 30 = $60

60 + 60 = $120
