Answer:
B. $25,069
Step-by-step explanation:
An interest of 6% per year, compounded monthly it means that he earns 6/12% = 0.5% of what he has invested every month.
If he invests x money what he will have the first month will be :
Money = x*(1+0.005)
The next month:
Money' = Money*(1+0.005) = x *(1+0.005)(1+0.005) = x* (1+0.005)^2
Therefore in this type of interest the formula is:
Money = x*(1+r)^n
Where:
x is the money invested the first time
r is the interest
n is the number of periods
For this problem:
x = what you have to find
r = 0.005
n = 3 years (1 period is 1 month) then the period is 36 months
Money = 30000
Replacing:
30000 = x * (1+0.005)^36
x = 25,069
25/5 = 5......so the unit rate is 5 teaspoons per cup
For the first one the answer is yes
Answer:
22/35
Step-by-step explanation:
-12/14=-6/7
-6/7*-11/15=66/105=22/35
The answer is 20%.
Step 1: Subtract the measured distance and the actual distance to calculate the error.Step 2: Divide the given value by the actual distance and convert it into the percentage.
the actual distance is 612 ftthe measured distance is 735 ft
Step 1: 735 ft - 612 ft = 123 ftStep 2: 123 ft / 612 ft = 0.20 = 20/100 = 20%
aka real answer 20.1%
