Chains, Inc. is in the business of making and selling chains. Let c(t) be the number of miles of chain produced after t hours of production. Let p(c) be the profit as a function of the number of miles of chain produced, and let q(t) be the profit as a function of the number of hours of production. Suppose the company can produce three miles of chain per hour, and suppose their profit on the chains is $4000 per mile of chain. Find each of the following (include units). a. c(t)=
b. c' (t)=

Aretha wanted to gather data about the cost of local bowling leagues in her area. she plotted the data and determined that the average bowling league costs consist of a one-time registration fee and a monthly fee modeled by the equation y = 15x + 20. identify and interpret the y-intercept in this model. the y-intercept is 20. this is the cost per month. the y-intercept is 20. this is the cost of registration. the y-intercept is 15. this is the cost of registration. the y-intercept is 15. this is the cost per month.

Ireally need subtract and simplify.(-y^2 – 4y - 8) – (-4y^2 – 6y + 3)show your work, ! i will mark you brainliest but you have to show your work.
