Evan earns $18 per hour. how much will he earn per hour after he gets a 5% raise? plz tell how u got it

$18 + $.9(5%) = $18.9
the thing with percentage is just moving decimals 100% = 1, 45% = .45, 10% = .1 and so on
so here you can solve it by taking 18 and multiplying it by .05(which is 5% if you understand my examples above)
.
or orally like i did, (note 10% is moving the decimal to the left one time so 10% of 18 is 1.8 and half of 1.8 is .9 which is 5% since the half of 10% is 5% lol )

Hello!

To find out how much Evan evan will earn after he gets a 5% raise, we must multiply his original pay ($18) by the percentage of raise he's getting (5%): 

$18 * 5% = $0.9

Now, add that amount onto his original pay: 

$0.9 + $18 = 18.9

Therefore, Evan will earn $18.90 after a 5% raise.
