Answer:
y = 
Step-by-step explanation:
Given
y + v = s ( subtract v from both sides )
y = s - v
Multiply through by 3 to clear the fraction
2y = 3s - 3v ( divide both sides by 2 )
y =

100=original
100-55=45
45% of oiriginal=29.99
percent means parts out of 100
45%=0.45
0.45 of original=29.99
divide both sides by 0.45
original=66.644444444444444444444444444444
round
$66.64 is original price

A simple way to solve fraction divided by while number problems is to multiply the denominator and the whole number together, but that only works if the numerator is 1, which in this case, they were all in fact, 1s.
Answer: number of tickets sold to adult = 566
Step-by-step explanation:
Let x = number of tickets sold by DCHS to students.
Let y = number of tickets sold DCHS to adults.
Tickets to Dundee crowns mr.dchs are $3 for students and $5 for adults.
This means cost of total tickets sold to students and adults is $3x and $5y respectively.
If DCHS collected $3943 for the tickets, then we have
3x + 5y = 3943 - - - - - -1
The number of adult tickets sold was 195 more than the number of student tickets. This means
y = x +195.
Put y = x +195 in equation 1
3x + 5(x+195) = 3943
3x + 5x + 975= 3943
8x +975=3943
8x = 3943-975= 2968
x = 2968/8 = 371
y = 371 + 195= 566
