Answer:
3 vegetable trays, 2 sandwich trays
Step-by-step 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
Answer:
I'm assuming you need to find how many you can buy, which is 2 sandwich trays and 3 vegetable trays
Step-by-step 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
