Cindy's parking garage charges $3.50 for weekday parking, and weekends are half price. If she parks in the garage 20 times per month, and three of these days are weekends, how much does she spend on parking per month?

To determine the total cost of Cindy's parking per month, we begin by addressing her parking frequency. She parks in the garage 20 times each month, with three of those days being on the weekend. This means she parks on weekdays for 17 days.

The parking costs for each type of day are:

• Weekday parking: $3.50 per day

• Weekend parking: Half price, which is $3.50 / 2 = $1.75 per day

Next, we calculate the total cost for each type of parking:

1. For the weekdays:

• 17 weekday trips at $3.50 each results in:

17 × $3.50 = $59.50

2. For the weekends:

• 3 weekend trips at $1.75 each results in:

3 × $1.75 = $5.25

Now, summing both amounts gives us the total monthly parking expense:

• Total cost = Weekday total + Weekend total

• Total cost = $59.50 + $5.25 = $64.75

The amount Cindy spends on parking per month is therefore $64.75, which aligns with the choice that reflects this total
