Answer:
Step-by-step explanation:
Let w represents the number of weeks that they spent money on entertainment.
Casey spends $50 a week on entertainment. It means that in w weeks, Casey spends $50w
Kelly spends 10% less than Casey. The value of 10% is
10/100 × 50w = 5w
The amount that Kelly spends would be
50w - 5w = $45w
Megan spends $5 less than Kelly. Therefore, the expression that represents how much Megan spends would be
45w - 5
