The middle value should be 4%.
The reason why is because if the value inside the parentheses was 1.00, it would be constant. 1.04 is equivalent to a positive change of 4%.
Also, it changes every 1 hour, instead of every 15 minutes, because the function is solving for variable t, which, in this context, represents the time in hours.

Answer:
45 members are in the choir.
Step-by-step explanation:
Set up an equation:
Variable x = boys
3/6 = x/30
Cross multiply:
3 × 30 = 6 × x
90 = 6x
Divide both sides by 6:
15 = x
There are 15 boys.
To find the number of members in the choir, add the number of boys and girls:
30 + 15 = 45
<span>5x ^2+ 15x = 0
</span><span>3x ^2 + 5x - 7 = 0
</span><span>x ^2 - 4x = 4x + 7</span>
