Two types of tickets are available for a charity ball event: $18 for a reserved seat and $9 for general admission. The number of reserved seats available is 85 less than the number of tickets available for general admission. If the sale of tickets for the day was $3600, how many seats were allotted for general admission?
1 answer:
Answer:
190 seats
Step-by-step explanation:
Firstly, we assign variables. Let the number of reserved seats be r and the numbers of general seats be g.
We have 85 more general seats than reserved seats. Mathematically,
g = r+ 85
Also we can form another equation with the cost of each seat
18r + 9g = 3600
Substitute the first equation into the second,
18r + 9(r + 85) = 3600
18r + 9r + 765 = 3600
27r = 3600 -765
27r = 2835
r = 2835/27 = 105
Now the number of general seats is 85 more than reserved seats. The number is this 85 + 105 = 190

Answer:
Q = P - n(x/100)
Step-by-step explanation:
P is the total number of lace edging, n is the number of times the length x is cut from P, and Q is the remnant of the reduction.
So the number of x length is subtracted from P and must be converted to meters (since it is in centimeters) to get Q. That is;
Q = P - n(x/100)
