A theater sells tickets for a concert. Tickets for lower-level seats sell for $55 each, and tickets for upper-level seats sell f

Alex

Answer: Lower level tickets = 85

Upper level tickets = 156

Step-by-step explanation: The first thing we shall do is assign letters to the unknown variables. We'll start by calling the lower level tickets L, and the upper level tickets P.

Next is we use the clues we've been given. Since the theater sold 241 tickets, we can write the expression

L + P = 241 ---------------- (1)

Next thing we're told is that lower level tickets were sold for $55 while upper level tickets were sold for $30. If total ticket sales was $9355, then we can write another expression

55L + 30P = 9355 -------(2)

We now have a pair of simultaneous equations

L + P = 241 ---------------------(1)

55L + 30P = 9355 ---------(2)

From equation (1), we shall make L the subject of the equation

L = 241 - P

Substitute for the value of L in equation (2), we now have

55(241 - P) + 30P = 9355

13255 - 55P + 30P = 9355

Collecting like terms we now have

13255 - 9355 = 55P - 30P

(Note that when a positive value crosses from one side of the equation to the other side, it becomes negative, and vice versa.

3900 = 25P

Divide both sides of the equation by 25

156 = P.

This means upper level tickets sold were 156 in number.

Substitute for the value of P in equation (1)

L + P = 241

L + 156 = 241

Subtract 156 from both sides of the equation

L + 156 - 156 = 241 - 156

L = 85

Therefore, lower level tickets sold were 85 and

Upper level tickets sold were 156

Alexander is blocking off several rooms in a hotel for guests coming to his wedding. The hotel can reserve small rooms that can

romanna [79]

Answer:

Small rooms=6

large rooms=10

Step-by-step explanation:

Let the number of small rooms be x

given alexander booked 4 more large rooms than the small rooms.

Therefore the number of large numbers be x+4.

Given each small room can accommodate 3 people.Therefore the total number of people in small rooms are 3x

Given each large room can accommodate 4 people. Therefore the total number of people in large rooms are 4(x+4)

Given total number of people accommodated=58

Total number of guests =number of guests in small rooms + number of guests in large rooms

$58=3x+4(x+4)$

$7x=42$

$x=6$

therefore the number of small rooms =6 and number of large rooms =10

Show and explain how you found the answer to this problem. Carla has 152 pictures to put in a scrapbook. If she can fit 12 pictu

jekas [21]

Explanation:

You make the equation. If she can put 12 on each page then you would multiply 12 by p (pages) and have it equal to 152

152=12p

To solve this, you would divide 12 from both sides

152/12=12.666

Therefore, 12.6=pages but since there aren’t 12.6 pages and you need to keep it a whole number you would round up to 13 because if you kept it at twelve pages you would have those pictures left over.
