8 0

Answer:

80

Step-by-step explanation:

Let the number of adults be x

Let the number of children be y

This means that the money paid by adults and kids is $5 multiplied by x (5x) and $2.50 multiplied by y (2.5y)

This will give two equations as shown below

x + y = 240  <em>total admissions......................... equation 1</em>

5x + 2.5y = 800  <em>total money paid..................equation 2</em>

<em />

<em>Making x the subject of formula in equation 1</em>

x=240-y<em>......................................................equation 3</em>

Substituting equation 3 into equation 2

5(240-y) + 2.5y = 800  <em>removing the brackets</em>

1200 - 5y + 2.5y = 800 <em>grouping like terms</em>

-5y + 2.5y = 800-1200  <em>simplifying </em>

-2.5y  = -400 therefore

-2.5y/-2.5 = -400/-2.5

y = 160

<em>Substituting y into equation 3</em>

x = 240 - y

x = 240 - 160

x = 80

Hence number of adults who attended = 80
