Question

Jen has a peanut butter sandwich on white bread each day. The number of calories C in the sandwich, as a function of the number of grams P of peanut butter, is C= f(P) = 174 + 6P. ( I need to answer questions (a) in the pic)

Answer 1

Given,

f(P)=174+6P

Given, P=1

Thus,

f(1)=174+6=180

It means the number of calories in the sandwich when 1 gram of peanut butter is used.
