Let f be amount of 43% and s be amount of 16%...
s+f=90, f=90-s
(.16s+.43f)/90=.25 using f found above we get:
(.16s+.43(90-s))/90=.25
.16s+38.7-.43s=22.5
-.27s=-16.2
s=60, and since f=90-s, f=30
So the chemist will need to mix 60ml of 16% solution with 30ml of 43% solution to create 90ml of a 25% solution.
Answer:
I think it's x > -5
Step-by-step explanation:
I think it's this because the dot starts at the 5 and points towards the 11. 11 is a bigger number than 5, the x is 11. The <u>> </u> means when something is grouped together and in this case, nothing's grouped together.

Answer:
Part A:
Rent = $7380
Mortgage payments = $9800
Insurance = $145
Taxes, insurance, maintenance = 
= $2830
Loss of Interest on security deposit = (650*6%) = $39
Interest lost on down payment and closing cost = (4,500*6%) = $270
Growth in equity = $225
Annual appreciation = $1700
Tax savings for mortgage interest = (9,575*28%) = $2,681
Tax savings for property taxes = (1,780*28%) = $498
Total rental cost = 
dollars
Total buying costs = 
dollars
Part B:
You should consider rent because the cost of renting is less than the cost of buying.
