High School Pre-Cal

Question

Martin won 8 tickets to the school carnival. He has a budget of $20 to buy additional tickets. Which function will determine the total number of tickets Martin can have?

 

A. F(x)= 20/x+a

 

B. F(x)= 20+8/x

 

C. F(x)= 20/x+8

 

D. F(x)= x/20+8

Answer 1

Okay. So Martin will definitely have the 8 tickets he won. In addition, he has $20 to buy more tickets. Let's say that each ticket that he buys costs x dollars. If they are $5 each, he could buy 4 tickets because $20/$5 = 4. Plus, he would still have the 8 he won initially.

 

Therefore, F(x) = 20/x + 8 would be the correct answer.
