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 dimesWhat 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)
Accepted Solution
A:
Answer: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 = 13x 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.
