Answer:
Step-by-step explanation:
Let x represent the amount invested at 3%. Then the total interest earned is ...
0.03x +0.02(25000 -x) = 510
0.01x = 10 . . . . . . . . . . . . subtract 500, collect terms
x = 1000
Mitchell invested $1,000 at 3% and $24,000 at 2%.
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

Ok? is the question your asking, for what x equals or what the equation equals
