Answer:
a = 242 adult and c = 52 children
Step-by-step explanation:
Solving as a system of equations.
a = adult
c = children
The adult and the children equal 294 people
a + c = 294
adult cost is 2.25 per adult
Total amount of adult is 2.25a because the number of adult are not given.
children cost is 1.75 per children
Total amount children is 1.75c because the number of children are not given
Total receipts $635.50.
a + c = 294 <em>multiply by -1.75</em> -1.75a - 1.75c = - 514.50
2.25a + 1.75c = 635.50 <em>does not change </em>2.25a + 1.75c = 635.50
<em>Add these equations together</em>
-1.75a - 1.75c = - 514.50
<u><em> </em></u><u>2.25a + 1.75c = 635.50 </u>
<em> </em> .50a = 121.00
a = 121.00/.50a
a = 242 adult
a + c = 294
242 + c = 294
c = 294 - 242
c = 52 children
Check: $2.25(242) + $1.75( 52) = $635 .50
$544.50 + $91.00 = $635.50
$635.50 = $635.50

Answer: 24 students are in the club.
Step-by-step explanation: Total number of ordered cases = 16 cases.
Each student in the club takes = 2/3 of a case.
<em>In order to find the number of students for 16 cases, we need to divide 16 2/3rd each.</em>
Therefore,
16 ÷ 2/3
Converting division sign into multiplication and flipping second fraction, we get
16 × 3/2 = 48/2 = 24.
<h3>Therefore, 24 students are in the club.</h3>
