Question

Melanie is at the fair and she is on a budget. She knows she will spend $5 to get in, $8 on snacks and the rest on tickets for games which sell for $0.75 per ticket. If she can spend a maximum of $20, then what is the most amount of tickets she can buy?

8 tickets

11 tickets

9 tickets

10 tickets

Answer 1

9 tickets

Explanation:

Let x = the number of tickets

let y = the total she spends

So y = 5 + 8 + 0.75x

If the max she can spend is 20, set y = 20 and solve for x:

5 + 8 + 0.75x = 20

13 + 0.75x = 20

0.75x = 20 - 13

0.75x = 7

x = 7 ÷ 0.75 = 9.333333333

Therefore, the max number of tickets that can be bough is 9
