Answer:
Greater than 21
Less than 45
Step-by-step explanation:
You add and subtract the two numbers you are given.
33 - 12 = 21
The third side has to be bigger than 21.
33 + 12 = 45
The third side has to be less than 45.

s + u = 28 This represent the number of candles sold
16s + 10u = 400 This represents the value of the candles sold
