Joe’s family is having a family reunion. 23 guys and 21 girls are going to ride vans out to the lake. Each van seats 10 people. How many vans do they need to rent so everyone has a seat?
23 + 21=44 people
44 people/ 10 people per van= 4 R 4 but you can't have any people left over so you need 5 vans.
They need 5 vans.
