department held its annual coin drop fundraiser at a streetlight. After one hour,
Keller had collected $42.50 more than Julia, and Israel had collected $15 less than
Keller. Altogether, the three firefighters collected $125.95. How much did each
person collect?
Find the solution using a tape diagram.
