It will take 16 weeks to collect 400 cans
So 16 multipled by 25 would give you 400
In order to solve the amount of each solution, we need to set up equations. We do as follows:
Let x = solution with 32% sodium
y = solution with 12% sodium
Overall balance
x + y = 50
Component balance
.32x + .12y = 50(.20) =10
Solving simultaneously,
x = 20
y = 30
Hope this answers the question. Have a nice day.
If he gave away 2/3 of 48, that means he gave away 32, leaving him with 16
If he gave away 3/4 of 16, he gave away 12, leaving him with 4
Answer: 4
I believe your answer would be
x^2 + 23x + 49
