Answer:
86
Step-by-step explanation:
I am pretty sure.
This ODE is separable:

Integrate both sides to get

Given that
, we get

Then




Started with: $60
left with: $10
items bought: 20
60 - 10 = 50 < amount spent
50/20 = amount spent/items bought
= $ 2.50 < each chocolate
you can check this by multiplying the items bought and the amount each item cost to get how much you spent
20 × 2.5 = 50
Stephanie started off with 60 dollars and ended with 10 dollars
60 - 50 = 10
hope this helps :)
The answer should be y < (-6 - 18x)/ -18

First we work out the brackets


Now we add -2x to both sides of the equation

Hence, the anser is
x > -8
