Step-by-step explanation:
Answer:
child buffet = $16, adult buffet =$23
Step-by-step explanation:
lets assume that child buffets costs, $x
and adult buffets costs $y
2x+4y= $124 .............this is our first equation
x+4y =$108 ................our second equation
<em>2x + 4y = 124</em>
<em>2x = 124 - 4y</em>
<em>x = 62 - 2y ....from first equation</em>
---------------------------------------------------------------------------------------------------
<em>x+4y =$108</em>
<em>x = 108 -4y ... from second equation</em>
---------------------------------------------------------------------------------------------------
now we will solve it through simultaneous equations
<em>62 - 2y = 108 -4y</em>
<em>2y = 46</em>
<em>y = $23</em>
<em>if y =$23</em>
<em>then x = 108 - 4(23)</em>
<em>x = $16</em>
