Genevie is buying dresses from an online website for a huge event coming up. She needs to buy 4 dresses, so that she can wear a different dress for each of the smaller parties leading up to the event. The website that she goes on is having a sale and is offering two different pricing plans. Genevie wants to know which plan is better in her case. The two pricing plans that the website was offering were:
PLAN A: $15 for each dress she buys plus a flat shipping rate of $10. ( y = 15n + 10)
PLAN B: $10 for each dress she buys plus a flat shipping rate of $20. ( y = 10n + 20 )
Independent Variable: # of dresses bought
Dependent Variable: Cost ( $ )
Point of Intersection: (2,40)
If Genevie was buying one dress then she should go with Plan A. If she were buying two dresses then it wouldn't have made any difference as to which plan she should have chose. If Genevie was buying more than 2 dresses then Plan B would have been the best option because she would be paying significantly less.
Since Genevie wants to purchase 4 dresses she should go with Plan B as she would be paying significantly less than if she were to go with Plan A.
