Riley has 15 tickets for rides at the fair. She wants to ride each of the
10 rides 3 times. She needs 4 tickets
for each ride. How many more
tickets does Riley need?
31
(Please answer, my brother needs help)

105 tickets more

Step-by-step explanation:

10x3=30

30x4=120

120-15=105

105

Step-by-step explanation:

Basically she wants to ride each of the 10 ride 3 times

So she will ride 30 times

Each ride = 4 tickets

So 30 rides = 120 tickets

She already has 15 tickets, so to find the amount of tickets Riley needs, we need to do 120-15, which is 105

Hope this helps your brother :)

Have a great day!
