Alright, let's do some math!
We know that the constant is = 25, and that for every 1 year it grows by 80.
So, we can create the formula h= 80y+25. This is a really simple way of saying that h is equal to 80 x the value of y + the base of 25.
Now we just need to plug in the numbers and we will get our answers!
y=5 80(5)+25= 425
y=7 80(7)+25= 585
y=9 80(9)+25= 745
y=10 80(10)+25= 825
I hope this helps! :)
Answer:
y=5,h=345. y=7, h=505. y=9, h=665. y=10, h=745.
Step-by-step explanation:
y=5
Add 320 to when it was first planted.
y=7
Add 160 to when y=5.
y=9
Add 160 to when y=7.
y=10
Add 80 to when y=9.
