Charlie is at an amusement park that has 18 different rides. Each ride costs $1.75. The function C(r) = 1.75r represents the total amount of money that Charlie will spend if he goes on r rides, but he never goes on the same one more than once. What domain and range are reasonable for the function? A. D : 0 ≤ r ≤ 31.5 R : 0 ≤ C(r) ≤ 18 B. D : 0 ≤ r ≤ 18 R : 0 ≤ C(r) ≤ 31.5 C. D : 1 ≤ r ≤ 18 R : 1.75 ≤ C(r) ≤ 31.5 D. D : 0 ≤ r ≤ 18 R : 18 ≤ C(r) ≤ 31.5

Domain= [0,18], Range = [0,31.50]

Step-by-step explanation:

If Charlie will only go to a single ride one time the possible rides he could go on would be 0 rides to all 18 rides for a domain of [0,18]. The output of the maximum and minimum x values would give us 0 dollars for riding 0 rides and 31.50 for riding all 18 (1.75 *0 = 0) and (1.75*18 = 31.50) so the range is [0, 31.50]

answer: the answer is one of

step-by-step explanation:   we are given to write a proper fraction where the whole is divided into an even number of equal parts less than ten, and an odd number of those parts exist.

an even number less than 10 may be one of 2, 4, 6 or 8. so, the whole may be one of these four evens.

now, an odd number of these parts must exist, so the numerator must be an odd number, one of 1, 3, 5 or 7. it cannot be 9 because then the fraction will become improper.

thus, our fraction may be one of the following
