Answer:
60 push-ups
Step-by-step explanation:
Set up a ratio to represent the problem:
Molly : Liza
10 : 15

10 : 15
x4 x4
40 : 60
So, Liza does 60 push-ups while Molly does 40.
The question is an illustration of inequalities.
The inequality that represents Lashonda's amount of exercise is: 
The given parameter is:

In inequality, at least means <em>greater than or equal to</em>.
So, the above equation becomes:

From the question, we understand that the number of minutes should be represented with t.
So, we have:

Hence, the inequality is:
