Final answer:
By dividing the number of surveyed people (144) by the given percent in decimal form (0.45), we find that the total number of customers is 320.
Step-by-step explanation:
To determine the total number of customers at the ice cream shop, we can use the information given to create a proportion. If 144 people surveyed represent 45% of the total customers, we can set up the following equation:
144 = 0.45 × Total Customers
We can solve for the total number of customers by dividing both sides by 0.45:
Total Customers = 144 / 0.45
Total Customers = 320
Therefore, the total number of customers who visit the ice cream shop is 320.
