Answer:
The total cost of 1 belt and 1 tie is $13 and $39 respectively.
Step-by-step explanation:
Given that,
The cost of 4 belts and 5 ties is $247.
Each tie costs 3 times as much as a belt.
Let the cost of a belt is x and that of a tie is y.
ATQ,
4x + 5y = 247 ...(1)
y = 3x ....(2)
Put the value of y from equation (2) in equation (1)
4x + 5(3x) = 247
4x + 15x = 247
19x = 247
x = 13
Put the value in equation (2)
y = 3x
= 3(13)
= 39
So, the total cost of 1 belt and 1 tie is $13 and $39 respectively.

Let’s start by finding the total amount of tickets sold
717+19+1=737
Now multiply by 5 to see how much money they initially brought in
737•5=3,685
Now let’s find the total expense of the prizes
166+(19•20)=t
166+380=546
Now subtract the expenses from the total ticket sales
3,685-546=3,139
They made $3,139 TOTAL
Now let’s divide the total made by the total tickets sold
3139 / 737 = 4.26
They made $4.26 PER TICKET
