Final answer:
Michelle can save $1020 in one year if she quits her fitness center membership.
Step-by-step explanation:
To determine how much money Michelle can save in one year if she quits her fitness center membership, we need to calculate the total amount she pays for the membership in a year and subtract it from the amount she would save. Michelle pays $85 per month for the membership, and there are 12 months in a year. So, the total amount she pays in a year is $85 x 12 = $1020. Therefore, if Michelle quits the fitness center, she can save $1020 in one year.
