Sarah and joe are seeking to join a gym. sarah saw on television that great gym is offering membership at $19.50 per month, plus a one-time registration fee of $59. joe plans to join workout world because workout world only charges $9.50 per month, plus a one-time registration fee of $149.

3. (20 points) if sarah decides to join great gym and joe joins workout world, who would pay less during the first month of membership? show your work.

Set up an equation for both Sarah and Joe.

Sarah's equation would be 59+19.50x=y

Joe's Equation would be 149+9.50x=y

The goal is to get y to equal the lowest number. If we plug in 1 for x for both equations we get:

59+19.50(1)=y for sarah and Joes would be 149+9.50(1)=y.

Sarah would pay $78.50 for her 1st month and Joe would pay $158.5 for his 1st month. Sarah pays much less than joe but over a few months Sarah would pay more eventually. Hope I helped and if you have any questions, just leave a comment.
