Question

Nathan has a $5 gift card to download Pokemon games. The function m =

-0.5d + 5 represents the amount of money m that remains on the card
after a certain number of games, d, are downloaded. Find the zero and
explain what it means.*

Nathan can download 9 games and have some money left on the card

Nathan can download 10 games and have $0 left on the card

Nathan can download 15 games and have some money left on the card

Nathan can download 20 games and have $0 left on the card

Answer 1

• B. Nathan can download 10 games and have $0 left on the card

Explanation:

Function given

• m = -0,5d + 5

Each game costs $0.5 so 10 games cost 10*0.5 = $5

• m = -0.5*10 + 5
• m = -5 + 5
• m = 0

Therefore when 10 games downloaded, no money is left on the card.

Correct choice is: B
