Question 133226
Since the person has to pay $150 no matter what, this is the fixed cost. Also, since the cost for each day is $100, this is the variable cost. So the equation would follow the form



S(x)=Variable Cost * x + Fixed Cost



So in this case the equation is 


{{{S(x)=100x+150}}}



{{{S(5.5)=100(5.5)+150}}} Now plug in {{{x=5.5}}} to evaluate S(5.5)



{{{S(5.5)=100(6)+150}}} Round 5.5 to 6 (remember, it's $100 per day or partial day)


{{{S(5.5)=600+150}}} Multiply



{{{S(5.5)=750}}} Add



So this means that when x=5.5 the cost is $750
