B. Which is the best type of graph to show the percentage of students who have blond, brown, black, or red hair?

-Pictograph

-Circle Graph

-Double Bar Graph

-Stem and leaf plot

C.The sum of two numbers is 25. Their difference is 11. What are the two numbers?

Solution

a)

let number of ham sandwiches sold =x

number of  turkey sandwiches sold =5+x

They sold 13 sandwiches in all

=>x+ 5+x =13

=>2x+5=13

=>2x=13-5

=>2x=8

=>x=8_/2

=>x=4

number of  turkey sandwiches sold =5+4

number of  turkey sandwiches sold =9

cafeteria sells 9 turkey sandwiches

============================================================

B)

Circle Graph is the best type of graph to show the percentage of students who have blond, brown, black, or red hair

==========================================================

C)

let 2 number be x, y where x>y

The sum of two numbers is 25. Their difference is 11.

x+y =25, x-y =11

=>x+y +x-y=25+11

=>2x=36

=>x=18

x+y=25, x=18

=>18+y=25

=>y=7

the two numbers are 7,18
