Rob pays $258 every 3 months for his karate lessons. at this rate, how much will rob pay for 3 years of karate lessons?

Well first divide 3 years into months and there are 36 months in 3 years, next divide 258 into 3 months and that is 86, next multiply 86 by 36 and you get 3,096 

Steps:
3 Years into months is 36
258 Divided by 3 is 86
86 Times 36 is 3,096

Answer $3,096

If he pays 258 every three month it means that he pays 1034(258x4) every year. Therefore in 3 years he will pay 1034 multiplied by three which is 3096
