Answer:
350 mL
Step-by-step explanation:
Let q represent the quantity (in mL) needed of the 70% solution. Then the total amount of mixture will be q+50 milliliters. The total amount of alcohol in the mixture will be ...
0.70q +0.30(50) = 0.65(50 +q)
.05q = 17.5 . . . . . . subtract (0.65q +1.50)
q = 350 . . . . . . . . . divide by 0.05
You will need 350 mL of the 70% solution.
= 0.4
because...
if you divide 6 by 3 it gives you 2.
then....
divide 2 by 5 and the answer is 0.4

Answer:
$6500
Step-by-step explanation
x = amount ($) loaned at 6%
then
18000-x = amount ($) loaned at 14%
.06x + .14(18000-x) = 2000
.06x + 2520-.14x = 2000
2520-.08x = 2000
-.08x = -520
x = $6,500
