1. Spotlight Video Rentals
Spotlight Video rents movies. After DVDs and VHS tapes have been viewed a
certain number of times, their quality deteriorates and they need to be replaced.
Spreadsheet
■ Number of times each title has been rented.
■ Number of defects that have been reported.
■ The percent acceptable must be above 85 percent based on usage. If the
percentage reported is above 85 percent, then Spotlight Video wants to flag this
video as “REPLACE.”

DVD Sales
Hans Hultgren, the sales manager for DVD Sales, wants to maximize his profit
on the sale of portable DVD players. He already has two portable models he
plans to sell:
Products Retail Price Wholesale Cost
Panasonic DVD–LS50 $349.95 $192.47
Mintek MDP–1810 $199.95 $109.99
Hans needs your help in calculating his maximum profit. First, he would like you
to use the Web to locate the retail price of two other portable DVD players not
listed in the table above. The wholesale price of each unit is 55 percent of the
retail price for both units you find. Hans has two constraints:
1. Hans has $200,000 to purchase new DVD players. The total wholesale cost of
the four types of DVD units must be less than $200,000.
2. Hans must purchase a minimum of 100 units of each player from his
wholesaler.
You want to use Excel Solver to maximize the total profit for Hans with the
constraints mentioned above and limiting the number of units to positive
integers.
A Min/Max problem can have more

Constraints
HotSprings Spas manufactures and sells two spa models: the Steamboat and the
Classic. HotSprings Spas receives spa bodies from another manufacturer and then
adds a pump and tubing to circulate the water. The Steamboat model demands
15.5 hours of labor and 14.5 feet of tubing. The Classic model requires 10.5 hours
of labor and uses 20 feet of tubing.
Based on selling patterns, the owner, Deborah, has determined that the
Steamboat model generates a profit of $400 per unit, and each Classic model
generates $345 profit.
While Deborah would like a large labor capacity and sufficient tubing and motors
to build any number of spas, her resources are limited. For the next production
period, Deborah has 2,650 labor hours, 3,450 feet of tubing, and 231 pumps
available. Deborah needs assistance in figuring out how many Steamboat and
Classic models to build in order to maximize her profit. Given the constraints
above, use Solver to assist Deborah in her what-if analysis..

A note on Solver
There can be no decision function between
the Variables (By Changing) and the Target in
a Solver model.
This includes IF, VLOOKUP, SUMIF and similar
functions
Automobile Budget
5. Budget Constraints
Joanne Krol wants to purchase a newer model automobile to replace her
rusty 1989 car. The bank where Joanne has a checking account, US Bank, is
advertising an annual interest rate of 6.75 percent for a three-year loan on
used cars. By selling her old car and using some cash she has accumulated,
Joanne has $3,000 available as a down payment. Under her current budget,
Joanne figures that the maximum monthly loan payment she can afford
is $300. She wants to find out the maximum car price she can afford and keep
the monthly payment no higher than $300. She cannot alter the interest rate
or the three-year term. Use the Excel Goal Seek command to figure out the
highest purchase price Joanne can afford.

When IF is not needed
• Jack get 5% commission if he sells up to
$1,000 but if he sells more than $1000 his
commission rate is 7%
• Let B5 hold his sales figure this month, and C5
his commission rate
• Try this =IF(B5<=1000,5%,7%).
• Now try =5% + (B5>1000)*2%
• Use Formula |
