Answer:
18500 is the initial value
Every year they increase by a factor of 1.03
Step-by-step explanation:
This is written in the form
y = ab^x where a is the initial value and b is the growth rate/decrease
y = (18500) (1.03)^t
The initial value is 18500
The students will increase by 1.03 - 1 = .03
The factor of increase is what they multiply by which is 1.03
1000/350 = $2.85
here I just divided the amount of candy bars she bought by the total cost.
value = 18000*(1-0.50)^3 = 2250
value after 3 years = $2250
