The constant rate of change is $1.75 :)
This is because when the x value equals 1 the y value equals 4.75. And when the x value equals 2 the y value equals 6.50, so the rate of change is between the 2 y values which is linear so it has a constant rate of change of $1.75.
Answer:
C
Step-by-step explain
My sister just had that question
5*6=20+y
30=20+y
30-20=20-20+y
10=y
Check answer by using substitution method
5*6=20+y
30=20+10
30=30
Answer is y=10
Like I said last time, find the difference of the two numbers which is .75.
Divide that by the original number 3.45.
Your answer is .0724 or 7.2%
