Answer:
50% of the solution
Step-by-step explanation:
25% of 100 ml = 25
added to 70 % of (100 - x) = 70 - 0.7x
we need to add 25 + 70-0.7x to get = 100 ml 60% i.e 60
now,
solve for x
0.7x =25+70-60
0.7x =35
x = 35/0.7
x= 50 % of the solution she needs to drain
This is a division problem:
Each box holds 20 bags.
800 bags / 20 bags per box = # of boxes
40 boxes are needed.
Is that suppose to be the problem?
$40 will be taken off the bill and you will be paying a total of $120.
Multiply 160 by .25 to find the amount taken off ($40), and then subtract from the total to find the amount that you will be paying ($120).
Have a great day!
