Answer:
A
Step-by-step explanation:
note that i = 
given
- 1 + 2i
= - 1 + 
= - 1 + 
John exercised 20% more than Toby. So the number of hours that John exercises per week is 14 + 0.2(14) = 14 + 2.8 = 16.8.
Jenny exercises two more hours than John. So the number of hours that Jenny exercises per week is 16.8 + 2 = 18.8.
So an expression representing the number of hours that Jenny exercises after w weeks is 18.8w.
25,000 x .04 = 1000 a year......
so 7,000 after 7 years
So, in 7 years she'll be making 32,000 a year
