Answer:
$4500
Step-by-step explanation:
Given data
State income tax= $234
we are told that the tax paid is 5.2% of her income
Let her earnings be x
so
5.2% of x = $234
5.2/100*x=234
0.052x= 234
x= 234/0.052
x= $4500
Hence her earnings is $4500

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.
Answer:
