Casey spends $50 a week on entertainment. kelly spends 10% less than casey and megan spends $5 less than kelly. which expression represents how much megan spends? (w represents weeks

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

walter needs to make at least 5 more cookies but no more than 40. 5 ≤ x ≤ 40

step-by-step explanation:

20 ≤ x + 15 ≤ 55

subtract 15 from all parts

20-15 ≤ x + 15-15 ≤ 55-15

5 ≤ x ≤ 40

this means how many more cookies he has to make

walter needs to make at least 5 more cookies, but no more than 40 cookies; 5 ≤ x ≤ 40
