Question

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?

А {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} ​

Answer 1

D is correct...

Good Luck!!

Answer 2

The answer will be D. It can’t be C or A because you cannot make $0.65 without a nickel. And not B because only 2 nickels is 10 cents and the dimes won’t make up the other 55 cents.
