Answer:
y=-3/4x+6
Step-by-step explanation:
12x+16y=96
16y=-12x+96
4y=-3x+24
y=-3/4x+6
<span>Part A
</span>Chorus:
Expontential growth = b*a^x
b = 15
a = 1.12 (a= r+1), r = 12%
Which gives a function of f(x) = 15*1.12^x
Band
Linear growth = ax+b
a = 2
b = 30
Which gives a function of g(x)=2x+30
<span>Part B:
</span>f(9) = 15*1.12^9 = 41.59
g(9) = 2*9+30 = 48
<span>Part C:
</span>This is probably problem solving, where you're allowed to use calculators and other softwares.
Therefore you can use different softwares, and make f(x) = g(x).

Step-by-step explanation:
original price (100%) → $19
discounted price ((100-75)%) = (25%) → 25% x $19 = $4.75
