Answer:
Step-by-step explanation:
f(x) = 1/2(4)^x
Plug in 3 for x
f(3) = 1/2(4)³
Cube 4.
4³ = 4 x 4 x 4 = 64
f(3) = 1/2(64)
Multiply 64 with 1/2 (or divide by 2)
f(3) = 64/2
f(3) = 32
24x .99 which equals $23.76
Hope this helps!
Ruben has 6 new books for his collection. This increases his collection by 12%
Let x be the number of books Ruben has before 6 new books added
x + 12% of x = x+6
x + 0.12x = x+6
1.12 x = x+6
Subtract x on both sides
0.12x = 6
Divide by 0.12
x = 50
6 new books are added for his collection
So 50 + 6 = 56
He have 56 books now.
