Question

In a collection of 50 cards, Sal has some valuable and some regular cards. He has 16 more valuable cards than regular cards. How many of each kind of card does Sal have? Explain the situation using an equation and solve.

Answer 1

Answer: 17 Regular, 33 Valuable

Explanation:

Given

Sal has 50 cards

He has 16 more valuable card than regular cards

Suppose he has x regular cards

So, valuable cards are x+16

Their sum must be 50

`\Rightarrow x+x+16=50\\\Rightarrow 2x=50-16\\\Rightarrow 2x=34\\\Rightarrow x=17`

Therefore, he has 17 regular cards and 33 valuable cards
