Ask your teacher .... no kidding but really just convert the numbers
Well every time it gets rid of a shell it grows 1 1/3 times larger. So so to see how much it grows after the first time you say
1 cm * 1 1/3 = 1 1/3 cm
to get the next one you do the same
1 1/3 cm * 1 1/3 cm = 16/9
It will keep going multiplying by 1 1/3. So so we can say in an equation that the
(initial size) * 1 1/3 *(number of shells) = length
Or 1cm * 1 1/3 * n = L
We we know the final length is 10cm
So 1 1/3 * n = 10cm
n = 7.5shells
so approximately 7 or 8 shells
Answer:
Slope = -3/4
y-intercept = 2
Step-by-step explanation:

So to find percent increase, you want to minus the difference in cost..
1.09- 0.87= .22...
now divide the difference by the original....
.22 ÷ .87 = .25287.....etc
now multiply that by 100...
.25287 × 100 = 25.287
now it says round to the nearest tenth so...
25.29% increase.
