(a)
To check:If any box longer than 30 inches costs $10 to wrap.
(a)
Answer to Problem 44PFA
It is true that any box longer than 30 inches costs $10 to wrap.
Explanation of Solution
Given information: The graph is given as,
A least integer function is plotted in the graph. It can be seen in the graph that any gift of length more than 30 inches costs $10 to be wrapped.
(b)
To check: If a box with a length of 318inches costs $8 to wrap.
(b)
Answer to Problem 44PFA
It is not true that a box with a length of 318 inches costs $8 to wrap.
Explanation of Solution
Given information: The graph is given as,
A least integer function is plotted in the graph. It can be seen in the graph that any gift of length more than 18 inches costs $8 to be wrapped, but a gist of length 18 inches will cost $6 only.
(c)
To check: If there are 4 different cost levels for gift wrapping.
(c)
Answer to Problem 44PFA
It is true that there are 4 different cost levels for gift wrapping.
Explanation of Solution
Given information: The graph is given as,
A least integer function is plotted in the graph. It can be seen in the graph that there are 4 different levels of cost starting from $4 then $6 then $8 and then $10.
(d)
To check: If wrapping a box with length 6 inches costs more than a box with length inches.
(d)
Answer to Problem 44PFA
It is not true wrapping a box with length 6 inches costs more than a box with length inches.
Explanation of Solution
Given information: The graph is given as,
A least integer function is plotted in the graph. It can be seen in the graph that the cost of wrapping a 4 inches length box and a 6 inches length box is same.
