andre [41]

Answer:

342.

Step-by-step explanation:

Let x represent the number of adults and y represent the number of senior citizens.

We have been given that on a recent weekend evening 514 people paid for the admission. We can represent this information in an equation as:

x+y=514...(1)

We have been given that the Family Fine Arts Center charges $20 per adult and $13 per senior citizen for its performances.

The cost of x adult tickets would be 20x and cost of y senior citizen tickets would be 13y.

We are also told that total receipts were $7886 on a recent weekend evening. We can represent this information in an equation as:

20x+13y=7,886...(2)

From equation (1), we will get:

We can represent this information in an equation as:

x=514-y

Substitute this value in equation (2) as:

20(514-y)+13y=7,886

10,280-20y+13y=7,886

10,280-7y=7,886

10,280-10,280-7y=7,886-10,280

-7y=-2394

\frac{-7y}{-7}=\frac{-2394}{-7}

y=342

Therefore, 342 senior citizens paid for the art center.

The price of a coat was reduced from $40 to $30. By what percentage was the price of the coat reduced?
Liula [17]

Answer:

The percentage that the coat was reduced is 25%.

Step-by-step explanation:

A percentage is always out of a factor of 100.

40 x 2.5 = 100

30 x 2.5 = 75

75/100 = 3/4

1/4 is missing, which is the percentage.

1/4 = 0.25, or 25%

Hope This Helps!
