Work backwards to solve

Question

Bart’s brother got paid every week. He always kept $85 for grocery and $35 for lunch and bus fare. He had $140 left. How much did he get paid every week?

Answer 1

If he has $140 left, you can add back in the $85 and $35 he held back to find his original amount.

$140 + $85 + $35 = $260
