Answer:
Adult required in the case of “a” 28 and in the case of “b” the adult requirement is 19.
Step-by-step explanation:
(a) The percentage of adult that support the change is 20 percent.
Now calculate the number of adult required.
Given p = 0.20
Use the below condition:
Since 35 adults are already there so required adults are 63 -35 = 28
(b) The percentage of adult that support the change is 25 percent.
Now calculate the number of adult required.
Given p = 0.25
Use the below condition:
Since 35 adults are already there so required adults are 54 -35 = 19

Answer:
$83,802
Step-by-step explanation:
The description is of an annuity due. Payments at the beginning of the period earn interest for the period, unlike those made at the end of the period.
<h3>Formula</h3>
The future value of an annuity due is given by the formula ...
FV = P(1 +r)((1 +r)^t -1)/r
where P is the annual payment, r is the annual interest rate, and t is the number of years.
This is essentially the sum of t terms of a geometric series with first term P(1+r) and common ratio (1+r).
<h3>Application</h3>
For P=$1000, r = 0.06, and t = 30, the future value is ...
FV = $1000(1.06)(1.06^30 -1)/0.06 ≈ $83,801.68
To the nearest dollar, the account value will be $83,802.

<em>Additional comment</em>
Spreadsheets and many graphing calculators have time-value-of-money (TVM) formulas built in. You need to make sure to choose the option that gives an <em>annuity due</em>, rather than an <em>ordinary annuity</em>. In the attached TVM picture, this setting is accomplished by PmtMode=1.
