Final answer:
By using the ratio of original to cinnamon pretzels sold and the number of original pretzels sold, it can be estimated that 84 cinnamon pretzels were probably sold.
Step-by-step explanation:
To estimate how many cinnamon pretzels the shop probably sold, we can use the ratio of original to cinnamon pretzels sold each hour, which is 11 original pretzels to 7 cinnamon pretzels. Since they sold 132 original pretzels today and we know the average per hour, we can first find out how many hours worth of pretzels that represents. We divide 132 by the hourly sale of original pretzels, which is 11, giving us 12 hours of sales.
Now, using this information, we can calculate the number of cinnamon pretzels sold by multiplying the number of hours by the average hourly sale of cinnamon pretzels, which is 7. So the calculation will be 12 hours multiplied by 7 cinnamon pretzels per hour, which equals 84 cinnamon pretzels.
