Provided :-
• I have $138
• I save $12 per week
• Friend have $ 98
• He saves $17 per week
Let the number of weeks required to have same balance be x
→ 138 + 12x = 98 + 17x
→ 138 - 98 = 17x - 12x
→ 40 = 5x
→ x = 8
So we need 8 weeks

Final savings = initial cost * savings / 100
Final savings = $213,500 * 18 / 100
Final savings = $213,500 * 0.18
Final savings = $38,430
