Answer 1

welcome to QC~ would you mind typing out the expression?

it should look something like

y = (initial salary)(1 + growth rate)^years

Answer 2

25,000(1.04)with that little t i couldnt find it on the desk top

Answer 3

well like we said before, the initial salary is the number before the parentheses 25,000

and the number inside the parentheses is 1 + growth rate

that being said what might the solution be?

Answer 4

im not sure

Answer 5

if 1.04 = 1 + growth rate

what's the growth rate?

Answer 6

2.5?

Answer 7

notice how we are adding 1 to the growth rate

so we do the opposite, subtract 1 to get

growth rate = 1.04 - 1 = ?

Answer 8

0.04

Answer 9

good, and as a percentage, this is 4%

so the initial salary is 25,000 and the growth rate is 4% making the answer choice..?
