This is calculated using the formula of: A = Pe(rt), where A is the total amount, P is the principal amount, e is mathematical constant approximately equal to 2.71828, r is the rate of interest, then t is the time in years.
Given we have the P as $12,000, r is 0.064 and t is 12, we expressed these values to the formula as;
A = Pe(rt)
A = 12,000.e(0.064 x 12)
A = 12,000 x 2.71828e
A = 12,000 x 2.155
A = $25,860
Therefore the money that Ann will have in 12 years is $25,860.

Answer:
see below
Step-by-step explanation:
x - 2/5= 7
Add 2/5 to each side
x - 2/5 + 2/5 = 7+2/5
x = 7 2/5
or if
( x-2) /5 = 7
Multiply each side by 5
(x-2) /5 *5 = 7*5
x-2 = 35
Add 2 to each side
x-2+2 = 35+2
x = 37
This is the Pythagorean identity, therefore 
.
The number of students who chose not to study Spanish in their senior year is 124.
In mathematics, a percentage is a number or ratio that can be expressed as a fraction of 100. If we have to calculate percent of a number, divide the number by the whole and multiply by 100. Hence, the percentage means, a part per hundred. The word per cent means per 100. It is represented by the symbol “%”.
Given that
56% Students studied Spanish, which means 44% did not study Spanish.
In mathematics, a ratio shows how many times one number contains another.
Hence if the ratio is:
56 : 44 = 14:11
Then, the number of students who did not study Spanish is:
(14/11)×98 = 124.
Therefore the correct answer is 124.
