Multiply 1.50 by x ( number of books read and add it to the 20:
Equation: y = 20 + 1.50x
Replace y with the amount she raised and solve for x:
59 = 20 + 1.50x
Subtract 20 from both sides:
39 = 1.50x
Divide both sides by 1.50:
x = 39 /1.50 = 26 books were read.

Answer:
Step-by-step explanation:
Answer:
- (D) 1.2^y ≥ 2
- (D) 4
Step-by-step explanation:
The revenue is multiplied by 1.2 each year, so after y years, it is multiplied by 1.2 y times, or 1.2^y. The appropriate choice of equation is ...
1.2^y ≥ 2
__
Taking logarithms, we get ...
y·log(1.2) ≥ log(2)
y ≥ log(2)/log(1.2)
y ≥ 3.80
It will take 4 years to at least double the company's revenue.
