Bao saved $179 a month. He saved $145 less than Ada each month. How much would Ada save in three and a half years?

Bao saved 179 dollars a month

Ada saved 145 dollars more than Bao a month

Let B = Bao

let A = Ada

=> B = 179 dollars

=> A = b + 145 dollars or 179 + 145

Now, find the total amount will ada save in 3 years and half

=> 3 years and half = (12 x 3) + 6 = 42 months

=> A = 179 + 145 x 42

=> a = 324 x 42

=> A = 13 608 dollars in 3 years and half.
