Question

HELP PLEASE! WILL MARK BRANLIEST!! (Answer is not 252, 168, or 1050) ASAP!!
What was the original number if after an increase of 40%, it became 420.

Answer 1

Answer:

300

Step-by-step explanation:

40% = 0.40

420/1.4 = 300

To check:

300 * 0.40 = 120

120 + 300 = 420

Answer 2

Answer:

300

Step-by-step explanation:

Let x represent the original number.

Then the number plus a 40% increase comes out to 1.40n.

This 1.40n = 420.  Solve this for n:

n = 420/1.40 = 300

the unknown (original) number was 300.
