Naomi got an email inviting her to join a fan club for her favorite singer. The fan club costs $7.50 a week. She decided not to join. How much did she save after a year? (1 point)
To calculate how much she saved after a year, we need to determine the total cost of the fan club membership for a year and then subtract that amount from her total expenses.
The fan club costs $7.50 per week, so the total cost per year is $7.50/week * 52 weeks/year = $<<7.50*52=390>>390/year.
Since Naomi decided not to join, she saved the total cost for a year, which is $390.
Therefore, Naomi saved $390 after a year by not joining the fan club.
