To find out how many push-ups Jada needs to do each day for the rest of the week, we can follow these steps:

First, we determine how many push-ups she has already completed. Jada does 30 push-ups on Sunday, so: \[ \text{Push-ups completed} = 30 \]
Jada's goal is to complete at least 100 push-ups for the week. Therefore, the number of push-ups she still needs to do is: \[ \text{Push-ups remaining} = 100 - 30 = 70 \]
The week has 7 days, and she has already completed push-ups on 1 day (Sunday). That leaves her with 6 days (Monday through Saturday) to do push-ups. Let \( x \) be the number of push-ups she does each day for the remaining 6 days.
The inequality to represent the total number of push-ups for the week is: \[ 6x \geq 70 \]
To solve for \( x \), we divide both sides of the inequality by 6: \[ x \geq \frac{70}{6} \approx 11.67 \]

Since Jada can only do whole push-ups, we round up to the nearest whole number. Therefore, Jada needs to do at least 12 push-ups each day for the remaining 6 days to meet her goal.

Thus, the best interpretation of the solution in the context of the problem is:

Jada needs to do at least 12 push-ups each day for the rest of the week to meet her goal.
