If Beth had $35 more, she would have $105. If Jan had $10 less, he would have the same money as Beth has. How much money do Beth and Jan have altogether?
Beth has $105 - $35 = $<T>subtract(105, 35)=70
Jan has $70 + $10 = $<T>add(70, 10)=80
So, Beth and Jan have $70 + $80 = $<T>add(70, 80)=150 altogether.
