1. At a concert, 3 adult tickets and 2 child tickets cost $167 whereas 2 adult tickets and 1 child ticket cost $103. Find the price of an adult ticket.
Elimination method
3a + 2c = 167
2a + c = 103
---------------------
a + c = 64
2a + c = 103
a = 39
Substitute it with the first equality
3a + 2c = 167
3(39) + 2c = 167
117 + 2c = 167
2c = 167 - 117
2c = 50
c = 50:2
c = 25
Now that we figured it out, adult ticket cost $39 and child ticket cost $25.

3. Flight tickets to Bali for 2 adults and 2 children cost Rp3.200.000. A child’s ticket costs Rp280.000 less than an adult’s ticket. If another family wants to buy the same tickets for 3 adults and 1 child, how much will the tickets cost?
Jawab:
Rp6.120.000
Penjelasan dengan langkah-langkah:
Diket:
misal -->
adults = x
children = y
x + y = 3.200.000 --> Flight tickets to Bali for 2 adults and 2 children cost Rp3.200.000
y = x - 280.000 --> A child’s ticket costs Rp280.000 less than an adult’s ticket
Dit: 3 x + y = ?
------------------------------------------JAWAB-------------------------------------------------
x+y = 3.200.000 ---> persamaan 1
y = x - 280.000 --> persamaan 2
-------------------------------------------------------------------------------------------------------
pindah y persamaan 2 ke kanan dan nilai 280.000 ke kiri
x-y = 280.000
persamaan 1 dikurang persamaan 2
2y = 3.480.000
y = 1.740.000
masukan ke persamaan 1
x + 1.740.000 = 3.200.000
x = 3.200.000 - 1.740.000
x = 1.460.000
maka masukan ke persamaan 3 x + y
3x + y
= 3 (1.460.000) + 1.740.000
= 4.380.000 + 1.740.000
= 6.120.000

19. A firm produces 400 units of output at a total cost of $1,200. If total variable costs are $1,000 : a. average fixed cost is 50 cents. b. average total cost is 50 cents c. average variable cost is $2 d. average total cost is $2.50 !
d.
Explanation:
Here, it is given that the quantity produced is 400 units.
The total fixed costs is $1200.Out of which, total fixed costs is $200.
So, the total variable cost is $(1200-200)=$1000.
Average fixed costs
= TFC/Q
= 200/400
0,5
average variable cost
=TVC/Q
=$1000/400
=$2.5
total cost
= TC/Q
= $1200/400
=$3
So, the average total cost is $3, the average fixed cost is $0.5 and the average variable cost is $2.5.
20. There are 7052 boys and adults at a carnival. There are 756 fewer girls than adults. There is an equal number of girls and boys. How many children are there at the carnival?
Terdapat sebuah karnaval. Dalam karnaval, jumlah anak laki-laki dan orang dewasa adalah 7052 orang. Banyaknya anak perempuan adalah 756 kurangnya dari banyaknya orang dewasa. Banyaknya anak perempuan sama dengan banyaknya anak laki-laki. Banyaknya anak-anak pada karnaval tersebut adalah 6296 orang. Angka ini diperoleh dengan konsep sistem persamaan linear tiga variabel (SPLTV).
Penjelasan dengan langkah-langkahDiketahui:
Jumlah anak laki-laki dan orang dewasa adalah 7052 orang.
Banyaknya anak perempuan adalah 756 kurangnya dari banyaknya orang dewasa.
Banyaknya anak perempuan sama dengan banyaknya anak laki-laki.
Ditanya: banyaknya anak-anak
Jawab:
PemisalanMisalkan:
x: banyaknya anak laki-lakiy: banyaknya anak perempuanz: banyaknya orang dewasaPersamaanJumlah anak laki-laki dan orang dewasa adalah 7052 orang → x+z = 7052Banyaknya anak perempuan adalah 756 kurangnya dari banyaknya orang dewasa → y = z-756Banyaknya anak perempuan sama dengan banyaknya anak laki-laki → y = xSPLTVx+z = 7052...(1)
y = z-756...(2)
y = x...(3)
Persamaan lainPersamaan (1) dapat dituliskan kembali menjadi:
x = 7052-z...(4)
Nilai zSubstitusi persamaan (2) dan (4) ke (3).
z-756 = 7052-z
2z = 7808
z = 3904
Nilai yGunakan persamaan (2).
y = 3904-756 = 3148
Nilai xGunakan persamaan (3).
x = 3148
Banyaknya anak-anak dalam karnavalJumlahkan nilai x dan y, yaitu:
x+y = 3148+3148 = 6296
Jadi, banyaknya anak-anak dalam karnaval tersebut adalah 6296 orang.
