If the 1496 kg order is 10% more than the previous order, it means that the 1496 kg order is 110% of the previous order. (We consider the previous order to be 100%, so we add the additional 10% to that.)
We can set up the proportion:
This compares previous order percent and amount to the newest order percent and amount.
Solve this by multiplying both sides by 1496 to find x = 1360.
The previous order was 1360 kg.
