If Sally had $20 less, she would have $80. If Jolly has $20 more, she would have $70. How much money do Sally and Jolly have altogether?
Think hard. Detailed solution:
150
Sally has $80 + $20 = $100.

While Jolly has $70 - $20 = $50.

Thus, Sally and Jolly have $100 + $50 = $150 altogether.

The answer: 150
