Answer:
805 total packages
Explanation:
The driver delivered 644 packages that were Internet orders. Lets let X be the total number of orders delivered. We are told that 80% of the total orders delivered were Internet orders. So let's express that as the following equation:
Internet Orders = (0.80)*X
Since we know the number of Internet orders, use that in the equation:
644 = (0.80)*X
X = (644/0.80)
X = 805 total packages delivered that day.
