Question 9
Elmo finds himself at a Coke machine on a hot and dusty Sunday. The Coke machine requires exact change-two quarters and a dime. No other combination of coins will make anything come out of the machine. No stores are open; no one is in sight. Elmo is so thirsty that the only thing he cares about is how many soft drinks he will be able to buy with the change in his pocket; the more he can buy, the better.
Based on the above data, answer the given subquestions.
If Elmo has 2 quarters and a dime in his pockets, he can buy 1 soft drink. How many soft drinks can he buy if he has 4 quarters and 2 dimes? _______________
