Jada has challenged herself to do at least 100 full push-ups this week. On Sunday, she does 30 push-ups. Her arms are sore, so she decides to do fewer push-ups on the remaining days of the week. She wants to do the same number of push-ups each day for the rest of the week. Write and solve an inequality for the number of push-ups Jada needs to do each day for the rest of the week to meet her goal of 100 push-ups.

Jada has already done 30 push-ups on Sunday.
She needs to do a total of 100 push-ups for the week.
So, the total number of push-ups she needs to do for the rest of the week is 100 - 30 = 70.
Since she wants to do the same number of push-ups each day for the rest of the week, she needs to do x push-ups for the remaining days.
Therefore, the inequality is:
x * (number of remaining days) ≥ 70
There are 6 remaining days in the week (Monday to Saturday).
So, the inequality becomes:
6x ≥ 70
Dividing by 6 on both sides:
x ≥ 70 / 6 = 11.67
Rounded to the nearest whole number, Jada needs to do at least 12 push-ups each day for the rest of the week to meet her goal.
Therefore, the best interpretation is:
Jada needs to do at least 12 push-ups each day for the rest of the week to meet her goal.
