966
894
1002
805
which option is ok? ​

Answer 1

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.
