You found a job that pays $12$12 per hour. after working for one year, you will get a 4%4% raise. what will be your new pay rate after one year?

So your rate is $12 per hour or 12/1. You need to find 4% of that to find your raise per day after a year. 

x/12  =  4/100

(we always put percentages over 100) 

multiply 12 by 4...=48  
Then divide by 100 to find 4% of 12

48/100=0.48  This is 4% of 12

REMEMBER: This is ONLY how much you got raised by, so you need to add $12 to that to find your rate per day after a year

Your new rate after a year is 12.48 per day.
