We can start by fingering out how many calories are in one chip. We know that there are 140 calories in one serving of chips which is approximately 11 chips.
Knowing this we can divide 140 by 11 which will give us the approximate amount of calories per chip.
140/11 = 12.73.
There is approximately 12.73 calories per chip so now we can multiply the amount of calories per chip by the amount of chips you ate which is 25.
12.73(25) = 318.25.
Therefore you have eaten 318.25 calories if you have eaten 25 chips which have a average of 12.73 calories per chip.
