If we let a = 9,
y(t) = A x 3^(t/9)
(i) If y(t) = 1000 a t = 0, then
1000 = A (3)^(0/a)
A = 1000
(ii) At t= 5
y(5) = 1000 (3)^(5/9)
y(5) = 1841
(iii) At y(t) = 100,000
100,000 = 1000 (3)^(t/9)
t = 37.7 years
(iv) Taking the derivative and substituting, t = 0 , and t = 10
for t = 0
dy/dt = 122 people/year
for t = 10
dy/dt = 414 people/year
9.47 - 8.75 = 0.72
You would be making an extra 72 cents an hour at the new job

Answer:
60x + 42y
Step-by-step explanation:
6(10x + 7y)
Use distribute property and multiply 6 to everything inside the parenthesis:
6 x 10x = 60x
6 x 7y = 42y
SO, 60x + 42y is the correct answer
