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.
Answer: 1/20
Step-by-step explanation:
Number of lemonades = 1
Total number of drinks = 20

<u>Please read below.</u>
Step-by-step explanation:
1. Let's calculate the unit price for each brand of diapers.
A. Stay-Dry: 108 diapers for US$ 25.18
Unit price = 25.18/108
<u>Unit price = US$ 0.23</u>
B. Uber-Soft: 180 diapers for US$ 39.14
Unit price = 39.14/180
<u>Unit price = US$ 0.22</u>
C. Cuddlies: 160 diapers for US$ 38.77
Unit price = 38.77/160
<u>Unit price = US$ 0.24</u>
<u>D. James should advise his mom to purchase Uber-Soft diapers, because the unit price is the lowest.</u>
