(a)
To find: The difference in the sales of yearbook and frames.
(a)

Answer to Problem 15STP
Explanation of Solution
Given information:
The given table is:
Calculation:
Calculate the table.
The sales of yearbook made to the 11th grade classes and 10th classes.
Difference in sales of yearbook made to the 11th grade classes and 10th classes.
546−464=82
Difference in sales of frames made to the 11th grade classes and 10th classes.
344−278=66
Therefore the difference in the sales of yearbook and frames 66 .
(b)
To find: the total number of yearbook and frames.
(b)

Answer to Problem 15STP
The total number of yearbook and frames is 1375 .
Explanation of Solution
Given information:
The given table is.
Calculation:
Calculate the table.
Total number of yearbook sold is equal to.
423+464+546+575=2008
Total number of frames sold is equal to.
256+278+344+497=1375
Therefore the total number of yearbook and frames is 1375 .
(C)
To find: the sales of yearbook and frames for each class.
(C)

Answer to Problem 15STP
The total number of sales of yearbook and frames is each class 36546$
Explanation of Solution
Given information:
The given table is.
Calculation:
Calculate the table.
Cost of a yearbook is equal to $48 and cost of a frame is equal to $18 .
The amount of sales of yearbook and frames for each class .
$48*423+$18*256=20304+4608=24912$$48*464+$18*278=22272+5004=27276$$48*546+$18*497=27600+8946=36546$@48*546+$18*344=26208+6192=32400$
Therefore the total number of sales of yearbook and frames is each class 36546$ .
