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.
