Hello from MrBillDoesMath!
Answer:
Interest paid = $ 1,713,568.73
Monthly p[payment = $4913.25
Discussion:
From the "compound interest formula:
A = final amount
P = Initial amount (Principal)
r = yearly interest rate
n = number of years of accumulation.
In our case,
A = 350000( 1 + .052)^35 =
350000 (5.90) = (approx)
$2,063,568.73
Interest = $2,063,568.73 - 350000 = $ 1,713,568.73
There are 35 *12 = 420 months in 35 years. So the monthly payment would be ($2,063,568.73 / 420) = $4913.25
Thank you,
MrB
Approximately 68% of a normal distribution lies within one standard deviation of the mean, so this corresponds to students with scores between

.
So first we assume that half is adult and have is student.
So
215 adult 215 student
Now since it said they were 70 less student tickets than adult tickets we subtract 70.
215 - 70 = 145
Now we add the 70 we subtracted from student tickets to the adult tickets.
215 + 70 = 285
So there were
285 adult tickets sold and 145 student tickets sold
I hope this helped. Have a great day!
