the marginal cost c’(q) (in dollars per unit) of producing q units is given in the following table.
q 0 100 200 300 400 500 600
c(q) 25 20 18 22 28 35 45
(a) if the fixed cost is $10,000, estimate the total cost of producing 400 units. (use left and right hand estimates.)
(b) how much would the total cost increase if production were increased one unit, to 401 units?

Matt and brian were solving a system of equations. they both noticed that the two lines had the same slope. brian said that because each line in the system had the same slope, the two lines had to be parallel, which meant the solution to the system was "no solution" matt disagreed, and said they should also look at the y-intercepts before determining how many solutions there were. who is correct?

Δabc is dilated by a scale factor of 3 with the origin as the center of dilation to form δa′b′c′. the slope of is -1.2. the length of is p units, the length of is q units, and the length of is r units. the slope of is . the length of is units.
