A store is having a sale. They are offering $15 off the purchase of 4 video games and 10% off if you are a first time customer.
The discounts could be applied in two different orders.
Which do you PREDICT would save you the most money?
Use intuition, don't calculate.
A you will save more by getting $15 off
B you will save more by getting 10% off
C You will save the same amount either way
Explain your answer
Based on intuition, option B - getting 10% off - is likely to save you more money.
If you purchase 4 video games, the $15 off results in a fixed discount of $15 regardless of the total price of the games. On the other hand, the 10% off discount is variable and depends on the total price of the games. If the price of the 4 video games is above $150, the 10% off discount would be greater than $15, resulting in you saving more money.
Therefore, it is reasonable to predict that option B would save you more money.
