Question

The function P(x) = 0.9x - 100 models the relationship between the number of pretzels x that a certain vendor sells and the profit the vendor makes. Find P(700), the profit the vendor makes from selling 700 pretzels.

Answer 1

we are given

The function  models the relationship between the number of pretzels x that a certain vendor sells and the profit the vendor makes

$P(x)=0.9x-100$

here

P(x) is profit

we have to find P(700)

so, we can plug x=700 into P(x)

we get

$P(700)=0.9*700-100$

$P(700)=630-100$

$P(700)=530$

so,

the profit the vendor makes from selling 700 pretzels is $530.........Answer
