Answer:
- a) P(x) = 32000*1.04^x
- b) $37435
- c) During year 7
Step-by-step explanation:
<u>Given</u>
- Initial pay = $32000
- Increase rate = 4%
a. <u>Formula</u>
b. Year 5 is after 4 years, so we are looking for the value of P(4)
- P(4) = $32000*1.04^4 = $37435
c. <u>P(x) = 40000, x = ?</u>
- 40000 = 32000*1.04^x
- 1.04^x = 40000/32000
- 1.04^x = 1.25
- log 1.04^x = log 1.25
- x = log 1.25 / log 1.04
- x = 5.69, this is 6 years after
The required number of the years is 6 + 1 = 7
Answer:
21
Step-by-step explanation:
Answer:
Abebe will be exact twice as old as Aster in 8 years.
Step-by-step explanation:
Since Abebe is 12 years old, and his sister Aster is 2 years old, there is a difference of 10 years between them (12 - 2). Therefore, the difference between the two implies that Abebe is exactly twice as old as her sister when she is 10 years old, and she is 20 years old (10 x 2 = 20).
Therefore, since 20-12 equals 8, Abebe will be twice as old as her sister Aster hers in 8 years.
Answer:
4 and 1/8, 4 and 2/12(or 1/6 simplified), 4 and 1/4, and 5 and 10/11
Step-by-step explanation:
4 and 1/8=412.5%
4 and 1/6=416 2/3%
4 and 1/4=425%
Answer:
66.3
Step-by-step explanation:
First, you need to find the 25% of $88.40.
88.40×25% (or) 25/100 = □/88.40
Solve that and you should get 22.10.
22.10 is 25% of $88.40
Finally, subtract your percent from original price and boom!
88.40 - 22.10 = $66.30
