Answer:

Step-by-step explanation:
The amount formula in compound interest is:

where:
P = principal amount
r = annual interest
n = number of compounding periods
t = number of years
We already know that:
P = $2000

t = 7 (number of years from 6th to 13th bday)
n = 4 (quarterly in a year)
Then,

The answer is A

Answer:
he needs 4,000 fake dollars
Step-by-step explanation:
right now he has enough to buy something for $60 so he needs another 220 fake dollars to have enough for a $68 item
This can be factored into (x+9)(x+5)/(x+9)(x+1)
once simplified, it's (x+5)/(x+1)
The denominator cannot be negative, so x≠-1
Therefore, the answer is C.
