Find the number of cards he needs to sell to earn a prize in category 4.

Answer to Problem 34PPS
Yumas must sell from 12 to 26 cards inclusive.
Explanation of Solution
Given:
Yumas is selling gift cards to raise money for a class trip. He can earn prizes depending on how many cards he sells. So, far, he has sold 34 cards. How many more cards does he need to sell to earn a prize in category 4?
Concept Used:
Yumas has already sold 34 cards. He wants to sell to get a prize in the category 4.
In category 4, the number of cards he must sell is 46 − 60 inclusive.
He must sell (42 − 34) to (60 − 34) inclusive.
Calculation:
He must sell (42 − 34) to (60 − 34) inclusive.
Thus, Yumas must sell from 12 to 26 cards inclusive.
