Answer: 75 students.
Step-by-step explanation:
In the data set we have a total of 10 + 8 + 7 + 5 = 30 students.
of those, 10 want to go to the park, the percentage is:
(10/30)*100% = 33.3%
Then, out of the 225, we can expect that a 33.3% (or 0.333 in decimal form) want to go to the park, this is:
N = 225*0.333% = 74.925
We can roud it up, and get N = 75
So Sally can expect that 75 students want to go to the park

P is the principal amount, $5200.00.
r is the interest rate, 6% per year, or in decimal form, 6/100=0.06.
t is the time involved, 9....year(s) time periods.
So, t is 9....year time periods.
To find the simple interest, we multiply 5200 × 0.06 × 9 to get that:
The interest is: $2808.00
