Trina's toy company charges $0.85 per pound to ship toys. part a: write an equation to determine the total cost, c, to ship p pounds of toys. use your equation to determine the cost of shipping 2 pounds of toys. (6 points) part b: if the company reduces the cost to ship toys by 0.05 per pound, write an equation to determine the total cost, c, to ship p pounds of toys with the reduced cost. (4 points)

c = 0.80p

Step-by-step explanation:

Trina's toy company charges $0.85 per pound to ship toys.

Part A :   We have to write an equation to determine the cost c for shipping of p pounds of toys.

∵ 1 pound toy's shipping cost is = $0.85

∴ p pound toy's shipping cost will be  = ( p × 0.85 )

So equation will be C = 0.85p

Now cost of shipping when p = 2 pounds will be

                                              c = 0.85 × 2

                                                 = $1.70

Part B :  If company reduces the shipping cost by $0.05 per pound then cost per pound will be = 0.85 - 0.05

                                     = $0.80

Now equation for the cost of p pound will be c = 0.80p

$12. that is my answer.

if we use a graphing calculator, there is only one such number that satisfies the conclusion of the mean value theorem, that is, a number such that

where the right-hand side is the average rate of change of f on the interval [0.5,0.75], which is the slope of the secant line.

in the attached graph, the black line is the secant line which has its slope as the average rate of change of f on [0.5,0.75], while the orange line is the only tangent line to the graph of f in the interval that satisfies the mvt conclusion.
