Sarah bought 3 first class tickets and 7 coach tickets.
Step-by-step explanation:
Given,
Number of people = 10
Total amount spent on tickets = $4830
Cost of each coach ticket = $270
Cost of each first class ticket = $980
Let,
x be the number of coach tickets
y be the number of first class tickets
According to given statement;
x+y=10 Eqn 1
270x+980y=4830 Eqn 2
Multiplying Eqn 1 by 270

Subtracting Eqn 3 from Eqn 2

Dividing both sides by 710

Putting y=3 in Eqn 1

Sarah bought 3 first class tickets and 7 coach tickets.

Answer:
120 for oxen, 80 for cows, 60 for calves
o = 2x
Step-by-step explanation:
3o + 4x + 6c = 260
x = 2c
o = 2x
6x + 4x + 3x = 260
13x = 260
260 / 13 = 20
3o = 6x = 120
4x = 80
6c = 3x = 60
o = 2x
