Algorithm Workbench Review Questions: 3-10
3. Write assignment statements that perform the following operations with the variables a, b, and c. * Adds 2 to a and stores the result in b * Set b= 2 +a * Multiplies b times 4 and stores the result in a * set a= b*4 * Divides a by 3.14 and stores the result in b * set b= 3.14/b * Subtracts 8 from b and stored the result in a * set a= b-8

4. Assume the variables result, w, x, y, and z are all integers, and that w = 5, x = 4, y = 8, and z = 2. What value will be stored in result in each of the following statements? * set result= x+y= 4+8 * set result=z*2= 2*2 * set result= y/x= 8/4 * set result= y-z= 8-2
5. Write a pseudocode statement that declares the variable cost so it can hold real numbers. * Floating-point variable cost.
6. Write a pseudocode statement that declares the variable total so it can hold integers. Initialize the variable with the value 0. * Declare Real price=99.95 * Display "the original price." * Input item original price * Display "price"
7. Write a pseudocode statement that assigns the value 27 to the variable count. * Count:=27
8. Write a pseudocode statement that assigns the sum of 10 and 14 to the variable total. * Declare Integer total=0 * Set total=10+14
9. Write a pseudocode statement that subtracts the variable down Payment from the variable total and assigns the result to the variable due. * Declare
