Question

@friedch1cken
Connie needs to burn at least 350 calories at the gym today. She can burn 25 calories per minute on the treadmill and 10 calories per minute on the elliptical trainer. Which inequality below can be used to find the possible combinations of time she could spend on each machine and still meet her goal of burning at least 350 calories?

25t - 10e => 350

25t + 10e <= 350

25t - 10e <=350

25t + 10e => 350

Answer 1

"At least" means we need to find an inequality with the \[\ge\] sign. Already, we have it narrowed down to either the 1st or 4th answer.
Since the two forms of exercises are adding burned calories together, we can disqualify the 1st answer choice as the correct one.
So, the correct answer choice is the 4th one, \[ 25t + 10e \ge 350 \]

Answer 2

Does that make sense?

Answer 3

yes!
