multiple evaluations in one formula utilizing percentages

In the attached worksheet, for the value in cell C3, I want to project how many of the cities contracted will fall into each of the categories in cells B72- B75. I would then want to multiply the corresponding value in cells C72-C75 and add the four products together to determine the projected amount of licensing fees for the month
• Assume 30% of the cities under contract will meet the criteria established in B72
• 30% will meet B73
• 30% will meet B74
• And finally, 10% will meet B75

Also, is it possible for whole numbers to line up with the accounting numbers? You can see the issue in rows 2 – 10. Or is it supposed to look like that to differentiate between the two types of values?

Hope I explained it well!
