A cereal factory has weekly fixed costs of $28,000. It costs $1.39 to produce each box of cereal. A box of cereal sells for $3.97. Find the rule of the cost function​ c(x) that gives the total weekly cost of producing x boxes of cereal. A. ​c(x)=1.39x   B. ​c(x)=28,000+2.58x   C. ​c(x)=28,000+1.39x   D. ​c(x)=28,000+3.97x

A contractor wants to rent a wood chipper from Acme Rental for a day for $150 plus $11 per hour or from Bell Rental for a day for $172 plus $9 per hour. Find a cost function in dollars for using each rental firm. (Let x be the number of hours for which the wood chipper is rented.) Acme   C(x) =        Bell   C(x) =        (a) Find the number of hours for which each cost function will give the same cost. ____hours

the sides of a square all have a side length of y.  Write a simplified function in terms of y for a rectangle whose length is twice the side length of the square and whose width is 2 units longer than the side length of the square. A(y)=

Suppose a gift basket maker incurs costs for a basket according to C(x)=18x+220. If the baskets are sold for $43 per basket, what is the revenue function? (Simplify the function, unsimplified will result in 0 credit) R(x)=
