Answer:
90 days.
Step-by-step explanation:
dy/dt = - 0.0032y
dy = -0.0032y dt
dy/y = -0.0032 dt
Integrating:
ln y = -0.0032t + c where c is some constant
y = e^(-0032t) + e^c
y = A e^(-0032t) where A is a constant.
At time 0 we can let y = 1 so in that case A = 1
When there is 0.75 of y left:
0.75 = e^-0032t
ln 0,75 = -0032 t
t = ln 0.75 / -0032
t = 90.

Answer:
True
Step-by-step explanation:
An input is always anything that equals a sum.
Input: Small-Medium-Large
Output: Prices
Estimate this product first. 7 times 2 would be 14; 7 times 3 would be 21. So the actual product must be about halfway between 14 and 21, or 17.5.
The actual product 7*2.6 comes out to 18.2 (which is fairly close to 17.5, but not close at all to 14).
