Question

Khalid has $30 to take his brother and his friends to the movies. If each ticket costs $4.00, and he must buy tickets for himself and his brother, what is the greatest number of friends he can invite?

Answer 1

Answer: 5 friends

Explanation:

Khalid has $30 and each ticket is $4.

He needs to buy for both himself and his brother which would reduce the money to:

= 30 - 4 - 4

= $22

If each ticket is $4, the number of friends he can invite is:

= Amount of money he has / Price per ticket

= 22 / 4

= 5.5 friends

You round down as they are human:

= 5 friends
