Number of $14 tickets sold = 1340
Number of $21 tickets sold = 1152
Number of VIP tickets sold = 134
Step-by-step explanation:
step 1 :
Let,
The equation is 14a + 21b + 41c = 48446 ----------(1)
Given,
Ten times as many $14 tickets were sold as VIP tickets.
⇒ 10c = a ---------(2)
step 2:
The number of $14 tickets sold was 54 more than the sum of the number of $21 tickets and VIP tickets.
⇒ a = 54 + (b+c)
⇒ a - 54 = b+c
Substitute a = 10c in the above eqn,
⇒ 10c - 54 = (b+c)
⇒ b = 9c - 54 -----------(3)
step 3 :
substitute (2) and (3) in eqn (1)
14(10c) + 21(9c - 54) + 41c = 48446
Solve for the c value,
140c + 189c - 1134 + 41c = 48446
370c = 48446 + 1134
c = 49580 / 370
c = 134
step 4 :
Substitute c=134 in eqn (2),
10c = a
10 [tex]\times[/tex] 134 = a
a = 1340
Substitute c=134 in eqn (3),
b = 9(134) - 54
b = 1206 - 54
b = 1152
step 5 :
∴ a = number of $14 tickets = 1340
b = number of $21 tickets = 1152
c = number of VIP tickets = 134
