42 costumers increased by 50% how do i solve it can you explain

Steps:

1. Do a proportion

X/42 times 50/100

2. Do 50 times 42 equals 2,100

3. Do 2,100 divided 100

4. 50% of the costumers equals 21

5. 42 + 21 = 62

6. The answer is

There are now 62 costumers

If 42 = x, your equation is x + x/2. This is because 50% is 1/2 of 100, so increasing by 50% means you add half of the original to itself. Your answer would then be 42 + 21 = 63.

That’s the drawn-out explanation. You could also multiply 42 by 1.5, as that equals 150%/the original increased by 50%. 1.5 (42) = 63.

Or multiply 1/2 of 42 by 3 since there are two 50%s of the whole, original 42, plus the extra 50% makes three.

The second option is quickest.
