24 glasses would be needed to fill up a 3 liter jub
Answer:
10
Step-by-step explanation:
first turn percent into decimal,
10/100 = 0.10
then multiply 100 x 0.10 = 10
so therefore 10% 0f 100 is 10
The system of equations becomes:
s + u = 28 This represent the number of candles sold
16s + 10u = 400 This represents the value of the candles sold
I think that is right I look it up and god bless have a great day
This is a lot of math to write.... so I'll just say the answer is -21 :D
