Finding Average Weekly Spending

A group of friends collected data on their weekly spending over a month. The recorded amounts, in dollars, for four weeks were as follows:

• Week 1: $20
• Week 2: $30
• Week 3: $25
• Week 4: $35

What was the average weekly spending in dollars for the four weeks?

To calculate the average spending, use the formula:

$$ ext{Average} = rac{ ext{Total Spending}}{ ext{Number of Weeks}} $$
