Question 135015
a. GOOD WORK


b. yes, but where is the answer from a? __ try (48/n)+3


c. right again


d. mugs times selling price __ (n-2)((48/n)+3) __ FOILing __ 48+3n-(96/n)-6 __ 42+3n-(96/n)


e. p=mm-c __ 22=42+3n-(96/n)-48 __ 28=3n-(96/n)



L2. subtracting 28 and multiplying by n __ 0=3n^2-28n-96



L3
a. n=[28 +- sqrt((-28)^2-4*3*(-96)]/(2*3) __ n=[28 +- sqrt(784+1152)]/6
__ n=(28 +- 44)/6 __ n=12 and n=-8/3


b. 48/12=4


c. 22/10=2.20


d. a negative number of mugs is not realistic
