Answers
The rate of change is 1500 $ per year
Step-by-step explanation:
YEAR SAVING
1 $1500
2 $3000
3 $4500
Keith's unit rate of change of dollars with respect to time = (3000 - 1500)/(2 - 1)
= 1500/1 = 1500
or ( 4500 - 3000)/(3 - 2) = 1500/1 = 1500
or (4500 - 1500)/(3 -1) = 3000/2 = 1500
The unit rate is 1500 $ per year

3 $4500
Keith's unit rate of change of dollars with respect to time = (3000 - 1500)/(2 - 1)
= 1500/1 = 1500
or ( 4500 - 3000)/(3 - 2) = 1500/1 = 1500
or (4500 - 1500)/(3 -1) = 3000/2 = 1500
