A new toy hits the local store. Sales (in tens) increase a steady rate for several months, then decrease at about the same rate. This can be modeled by the function S(m)=−0.625|m−8|+5 In what month(s) were 25 toys sold?

Absolute value cannot be less than 0. No solution

Solution:

Given that,

A new toy hits the local store

Sales (in tens) increase a steady rate for several months, then decrease at about the same rate

This can be modeled by the function:

In what month(s) were 25 toys sold?

Therefore,

S = 25

Substitute S = 25 in above function

Thus no solution occurs
