A factory increased its production by 22.5% and produced 4900 tonnes .How many tonnes was it producing before?​

Answers

Answer:

It produced 3797.5 tons before.

22.5% of 4900 is 1102.5

That subtracted from 4900 is 3797.5 tons

Answer:

4000 tonnes.

Step-by-step explanation:

A 22.5% increase would be equal to a 1.225x production increase, so the production before the increase, x, would be x * 1.225 = 4900. To solve for x, divide both sides by 1.225.
