Question 814082
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
