General admission to the state fair of texas is $16.00. for guests to ride the various rides, they must use coupons that cost $0.50 each. the number of coupons needed for each ride varies. the representative function for the situation is c(x) = 0.5x + 16, where c(x) represents total cost as a function of the number of coupons, x. what is the domain for visiting and riding rides at the state fair of texas?

a. x ≥ 0, where x is an integer
b. x ≥ 0, x is non-negative
c. x is all real numbers
d. x ≥ $16.00

A

Step-by-step explanation:

Well, x is the number of coupons (tickets).

Can u buy fractional tickets? NO!

So you can buy 1 coupons, 2 coupons, 3 coupons etc.

We can certainly eliminate C and D.

Now what is the differnce in A and B??

A includes x = 0 and B doesn't.

Well, can you buy 0 coupons? YES! You can just go to the fair and decide NOT to ride anything. That situation is x = 0. So certainly A is the correct domain.

walter needs to make at least 5 more cookies but no more than 40. 5 ≥ x ≥ 40;

step-by-step explanation:

walter has to make a minimum of 20 cookies. he already has 15 cookies made, so he must make 5 more to meet the minimum.

the maximum amount of cookies he can make is 55. he already has 15, so he has to make no more than 40 more cookies to meet the maximum.
