4
2.5
10
None of the above

10. (TCO 2) Review the partial pseudocode below. What is the correct math expression to complete the algorithm and total sales for both regions?
Prompt “Enter total sales for region 1: ”
Input region1
Prompt “Enter total sales for region 2: ”
Input region2
Set _____
Display “total sales: ” + total (Points : 4)
total = region2
total = region1 * region2
total = region1 + region2
total = region1
