a. 1

b. 2

c. 3

d. 4

Answer 1

There are four possible combinations of nickels, dimes, and quarters for $0.50 in change for a DVD purchase.

Step-by-step explanation:

Zack needs to receive $0.50 in change, and we want to find out the combinations of nickels, dimes, and quarters that can make up this amount. Since there are 100 cents in a dollar, $0.50 is the same as 50 cents. Let's go through the possible combinations:

• 2 quarters (25 cents each) = 50 cents
• 1 quarter (25 cents), 2 dimes (10 cents each), and 1 nickel (5 cents) = 50 cents
• 1 quarter, 1 dime, and 3 nickels = 50 cents
• 5 dimes = 50 cents

Therefore, there are 4 possible combinations of quarters, dimes, and nickels that Zack can receive as change for a DVD purchase.
