Give the step-by-step reasoning process and then the final answer. Isabella has $45 more than Sam but only $15 more than Giselle. If Giselle has $120, calculate the total amount of money each shopper will receive if Isabella, Sam, and Giselle donate the money to three shoppers at their local town's supermarket who then decides to share it equally.
If Isabella has $15 more than Giselle, she has $120 + $15 = $135. Combined, Isabella and Giselle has $135 + $120 = $255. Isabella has $45 more than Sam, meaning Sam has $135 - $45 = $90. Together, Sam, Isabella, and Giselle has $255 + $90 = $345. if they donate the money to three shoppers at their local town's supermarket who share it equally, each shopper will receive $345 / 3 = $115.
The final answer: 115.
