Question

A car factory produces 100 cars in a day. If c is the total number of cars produced in d days, which equation represents the number of cars as a function of the number of days?.
a.d = f(c) = 100c.
b.d = f(c) = 100 + c.
c.c = f(d) = 100d.
d.c = f(c) = 100d.
e.d = f(c) = 100 – d

Answer 1

For this case we have the following variables:

d: number of days

c: total number of cars

We know that an amount of 100 cars per day is produced.

Therefore, the equation that models the problem is:

$c = 100d$

We can write this equation as a function of the number of days.

Therefore, by rewriting the equation we have:

$c = f (d) = 100d$

Answer:

An equation that represents the number of cars as a function of the number of days is:

$c = f (d) = 100d$

option c

Answer 2

We have:
c - the total number of cars,
d - the number of days;
c = f ( d ) = 100 d
Answer: C )
