Final answer:
By setting up a proportion and solving it, we find that Coffee Jo received a total of 250 orders on Monday, with 75 being online app orders, which represents 30% of the total orders.
Step-by-step explanation:
If 30% of Coffee Jo's orders come through their online app and we know that on Monday, Coffee Jo received 75 orders through their app, we can set up a simple proportion to find out how many total orders they received. To find the total number of orders, we would set up the proportion: 30% / 100% = 75 / Total Orders
Next, we cross-multiply to solve for the Total Orders: 30 * Total Orders = 75 * 100, Total Orders = (75 * 100) / 30, Total Orders = 7500 / 30, Total Orders = 250. Therefore, Coffee Jo received a total of 250 orders on Monday.
