Question

(I need the work too please!)

The yearly cost for cross-fit classes is $250 more than yoga classes. And, the
yearly cost for a gym membership is $100 more than yoga classes. Combined,
the cost for all the different plans are $1250. Determine the cost of the gym
membership, yoga, and cross-fit classes.

Answer 1

I am not sure if this was the correct method to solve the question, however it gives the right results if you check it.

Explanation:

3x+250+100=1250

3x= 900

x=300

yoga: 300, cross fit: 550 (300+250), gym: 400(300+100)
