The two inequalities formed will be:
One for ticket quantity:
x + y ≤ 600

One for funds generated via tickets:
5x + 7y ≥ 3500

Equating x to 330,
5(330) +7y ≥ 3500
y = 265

Checking if the other inequality holds true:
330 + 265 ≤ 600
595 ≤ 600

This inequality is still true so they can sell 265 tickets on the event day and cover their expenses.

Jayden earned some money doing odd jobs last summer and put it in a savings account that earns 12% interest compounded monthly.

Answer:

$220.18

Step-by-step explanation:

The amount A(n) accrued for P dollars saved at r% annual interest for a period of n years compounded k times is derived using the formula:

$A(n)=P \left(1+\dfrac{r}{k}\right)^{nk}$

In Jayden's case:

A(n)=$400
r=12%=0.12
n=5 years
k=12 Months

We want to determine the amount Jayden put in the savings account.

$400=P \left(1+\dfrac{0.12}{12}\right)^{12*5}\\400=P \left(1+0.01}\right)^{60}\\400=P \left(1.01}\right)^{60}\\P=\dfrac{400}{\left(1.01}\right)^{60}}\\$
