Answer: [tex]\$64.75[/tex]
Step-by-step explanation:
You know that for weekdays parking the price is $3.50 and weekends are half price. Then for weekends, the price is the following:
[tex]\frac{\$3.50}{2}=\$1.75[/tex]
You know that Cindy parked in the garage 20 times per month, and three of these days were weekend days. This means that she parked 17 times in week days and 3 times in weekends days.
Therefore, the total amount of money she would spend on parking per month can be calculated with:
[tex]Total\ per\ month=17(\$3.50)+3(\$1.75)\\\\Total\ per\ month=\$59.5+\$5.25\\\\Total\ per\ month=\$64.75[/tex]
