Question 814082: I need help setting up these word problems: 1.) Adult tickets to a pay cost of $22. Tickets for children cost $15. Tickets for a graph of 11 people cost a total of $228. Write and solve a system of equations to find how many children and how many adults were in the group.
2.) A school is planning a field trip for 142 people. The trip will use six drivers and two types of vehicles: buses and vans. A bus can seat 51 passengers. A van can seat 10 passengers. Write and solve a system of equations to find how many buses and vans will be needed.
3.)In talent show of singing and comedy acts, singing acts are 5 minutes long and comedy acts are 3 minutes long. The show has 12 acts and lasts 50 minutes. How many singing acts and how many comedy acts are in the show?

You can put this solution on YOUR website! 1.) Adult tickets to a pay cost of $22.
Tickets for children cost $15. Tickets for a group of 11 people cost a total of $228.
Write and solve a system of equations to find how many children and how many adults were in the group.
let a = no. of adults
let c = no. of children
Two equations
a + c = 11
a = (11-c), use this form for substitution
and
22a + 15c = 228
:
2.) A school is planning a field trip for 142 people.
The trip will use six drivers and two types of vehicles: buses and vans
. A bus can seat 51 passengers. A van can seat 10 passengers.
Write and solve a system of equations to find how many buses and vans will be needed.
b = no. of buses
v = no. of vans
Two equations
b + v = 6
v = (6-b)
and
51b + 10v = 142

3.)In talent show of singing and comedy acts,
singing acts are 5 minutes long and comedy acts are 3 minutes long.
The show has 12 acts and lasts 50 minutes.
How many singing acts and how many comedy acts are in the show?
let s = no. of singing acts
let c = no. comedies
Two equations
s + c = 12
c = (12-s)
and
5s + 3c = 50
