Question

Makayla has $8 to buy tickets at the school fair. Each ticket costs @1.5. Which inequality best represents how many tickets she can buy?

n=number of tickets

a. n<=5 b. n<8 c. n<=6 d. n<5

Answer 1

`n\le 5`

Explanation:

Let n be the number of tickets Makaya has to buy.

If the cost of one ticket is $1.5, then the cost of n tickets is $1.5n.

Makayla has $8 to buy tickets at the school fair, thus

`1.5n\le 8\\ \\n\le (8)/(1.5)\\ \\n\le (80)/(15)\\ \\n\le (16)/(3)\\ \\n\le 5(2)/(3)`

The maximum number of tickets Makaya can buy is 5, so

`n\le 5`
