You have to write a equation that represnts the problem whoch would start with f(x)=. Then you would put in the right numbers which is $2,500 for a one time labor fee and a $50 for every year book printed. In this case the x would go with the 50 since you dont know how many yearbooks are going to be printed. Hope I could help and have a nice day
Percent of decrease : Original - New / Original so... 80 - 52 / 80 ----> 28/80 .35 multiply by 100 to get percent 35% increase Hope I helped if you have any questions let me know! :)
