Question

1. Caroline practices piano as much as 2 hours a day Monday through Thursday, and she practices up to 3 hours on Sunday. Write an inequality to show the number of hours that she practices in one week. ​

Answer 1

Caroline practices piano up to 11 hours per week, with the inequality representing this being 0 ≤ P ≤ 11.

Step-by-step explanation:

The question asks us to write an inequality to represent the number of hours Caroline practices piano in one week. Caroline practices 2 hours a day from Monday to Thursday, which equates to 2 hours × 4 days = 8 hours. On Sunday, she practices up to 3 hours, therefore, the maximum hours she practices per week is 8 hours from Monday to Thursday plus 3 hours on Sunday, giving a total of 11 hours.

The inequality that shows the number of hours Caroline practices in one week (P) is:
0 ≤ P ≤ 11.

This indicates that Caroline practices at least 0 hours and at most 11 hours in a week.

Answer 2

Step-by-step explanation:

2 hours a day for M-Th would be 8 hours. Sunday >up to< 3 hours. In 1 week, you'd have the 4 days ×2hrs ea day plus the 3hrs from Sunday... In one week she (assuming she did the full 3hrs) would have done 11hrs of piano practice. Not sure completely what to do but that's my first part that I do to figure it out if that helps any...
