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)

    Step-by-step explanation:

    dimes only cannot give total ending in 5 cents

    so theres at least 1 nickel

    n by the same reason, no. of nickels must be odd no.

    most nickels is 0.65/0.05=13

    combining the above, ans is 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.
