Answer:
110
Step-by-step explanation:
Set hamburgers<em> </em>as <em>h,</em>
salted pretzels as <em>p</em>,
hot dogs as <em>d.</em>
h+p+d=144
(3.00)h+(2.25)p+(2.00)d=354.25
=>3h+2.25p+2d=354.25
we also know (2.00)d=82 => d=41
We make 3h+2.25p+2d=354.25 => 3h+2.25p=272.25
and h+p+d=144 => h+p=103
Set h=p-103
Substitution
3(p-103)+2.25p=272.25
3p-309+2.25p=272.25
(5.25)p=581.25
p=581.25/5.25=110.7142857
We round down =>110.
$2.40 for binding
10 cents ($0.10) per page
cost=binding+pagescost
binding=2.40
pagescost=costperpage X number of pages=0.10*n if n=number of pages
so
cost=0.10n+2.40
or
C(x)=0.10n+2.40
the fixed cost is the binding
Answer:
thats right.
