Give the step-by-step reasoning process and then the final answer. Bianca worked for 12.5 hours last weekend. Celeste worked for twice that amount of time and McClain worked 8.5 hours less than Celeste. How many minutes did the 3 people work in total?
Bianca = 12.5 hours. Celeste 2 * 12.5 = 25 hours. McClain = 25 - 8.5 = 16.5 hours. Total + 12.5 + 25 + 16.5 = 54 hours. 54 hours * 60 minutes = 3240 minutes. Bianca, Celeste and McClain worked a total of 3240 minutes last weekend.
The final answer: 3240.
