we know that
The simple interest formula is equal to

where
P is the Principal amount of money to be invested
I is the amount of money in interest
r is the rate of interest
t is Number of Time Periods
in this problem we have

substitute in the formula above and solve for P

![P=14.65/[(0.025)(2)]](https://tex.z-dn.net/?f=P%3D14.65%2F%5B%280.025%29%282%29%5D)

therefore
<u>the answer is</u>

Answer: No, there isn't a proportional relationship.
Step-by-step explanation: In these type of problems, always divide. For it to be proportional, the number of children/ apple slices should be the same for all days. But it isn't, the value differs.
Number of adult tickets sold is 31 and number of child tickers sold is 19
Step-by-step explanation:
- Step 1: Find the equation to find the number of child and adult tickets sold.
Let the number of adult tickets sold be x, then the number of child tickets will be 50 - x. (Since there is a total of 50 seats)
Charge for a child ticket = $2
Charge for adult ticket = $5
Total amount received from show = $193
Equation ⇒ 2(50 - x) + 5x = 193
- Step 2: Solve the equation to find x.
⇒ 100 - 2x + 5x = 193
⇒ 3x = 93
∴ x = 93/3 = 31
⇒ 50 - x = 50 - 31 = 19
