1. collin noticed that various combinations of nickels and dimes could add up to $0.65.

let x equal the number of nickels
let y equal the number of dimes

what is the domain where y is a function of x and the total value is $0.65?

a. (0,1,2,3,4,5,6,7,8,9,10,11,12,13)
b. (1,2,3,4,5,6,7,8,9,10,11,12,13)

c. (0,1,3,5,7,9,11,13)

d. (1,3,5,7,9,11,13)

Step-by-step explanation:

As  y is a function of x, the domain is the range of possible values for the independent variable, x.

x equals to the number of nickels and the total value is $0.65.

So the largest possible value for x = $0.65/$0.05 = 13

x must also be an odd number to make the total value at $0.65.

So the range of x is from 1,3,5,7,9,11,13.

The answer is D.
