Linear Equations and functions 16 - (S pts.) Suppose Mary makes tie dyed shirts that cost her 510.00 each and she has a fieed cost (the machine, the rent...) of 5400 per month. Suppose she sells each shirt with 1007 . markup namely at $20.00. If x is the number of shirts she makes (and aiso the number she selv) write down the cost and revenue functions: (hint: they are both linear functions) ( no work = no credit) C(x)= R(x)= b) How many shirts she has to sell to break-even? (Hint: solve C(x)=P(x) ) Work
