Answer to Problem 1STP
The piecewise defined function that represents the cost C of shipping package that weighs p pounds is
The correct option is (A).
Explanation of Solution
Given:
The shipping rate upto one pound is $8.50.
The cost of each additional pound is =
Calculation:
The standard form of slope and intercept form of the straight line is
Here m is the slope of the straight line and c is the y- intercept of the equation.
The initial shipping cost is the intercept of the line on the y- axis while the additional per pound cost is the slope of the equation.
Write the equation for the given situation.
Substitute
The equation of the straight line in the slope and intercept form is
The function can be written as
Therefore, the correct option is (A).
