For the past month, Tara recorded the number of days she went to work each week and the number of coffee shops she drove by during those days. How many coffee shops does she drive by each day?
Number of Days: 2, Number of Coffee Shops: 6
Number of Days: 5, Number of Coffee Shops: 15
Number of Days: 7, Number of Coffee Shops: 21
Tara drives by ___ coffee shops each day
Number of Days: 2, Number of Coffee Shops: 6
Number of Days: 5, Number of Coffee Shops: 15
Number of Days: 7, Number of Coffee Shops: 21
Tara drives by ___ coffee shops each day
We can set up a proportion using the number of days and the number of coffee shops to find out how many coffee shops Tara drives by each day.
Let x be the number of coffee shops Tara drives by each day.
Using the second set of data (5 days and 15 coffee shops), we can set up the proportion:
2 days / 6 coffee shops = 5 days / 15 coffee shops
2/6 = 5/x
Cross multiplying gives us:
2x = 30
x = 30 / 2
x = 15
Therefore, Tara drives by 15 coffee shops each day.
Let x be the number of coffee shops Tara drives by each day.
Using the second set of data (5 days and 15 coffee shops), we can set up the proportion:
2 days / 6 coffee shops = 5 days / 15 coffee shops
2/6 = 5/x
Cross multiplying gives us:
2x = 30
x = 30 / 2
x = 15
Therefore, Tara drives by 15 coffee shops each day.
