Question

Suppose that an empty crate weighs 2 kilograms. A typical orange weighs about 0.2 kilogram. The total weight of the crate with oranges is 10 kilograms. How many oranges are in the crate?

Answer 1

10kg - 2kg = 808/0.2 = 40

Answer 2

0.2x + 2 = 70....x = number of oranges
0.2x = 70 - 2
0.2x = 68
x = 68/0.2
x = 340 <===
