One gym charges $40 per month and $3 per exercise class. Another gym charges $20 per month and $8 per exercise class. After how many classes will the monthly cost be the same and what will the cost be?
Its a Systems Question.


Sagot :

y=3x+40
y=8x+20
when they are the same
3x+40=8x+20
x=4
so at 4 sessions they will be the same but the one that charges 8 per class will become more costly
