Explanation
To solve a Rates & Work problem with multiple workers, modify the standard formula Work = Rate × Time to this:
Work = Individual Rate × Number of Workers × Time
Solve for an individual chef’s rate, using the fact that 8 chefs produce 3,200 tarts in 5 days:
Work = Individual Rate × Number of Workers × Time
3,200 tarts = (R)(8)(5 days)
R = 80 tarts per day
That is, each chef can produce 80 tarts per day. Plug that rate back into the formula for each of the quantities:
Quantity A
Work = Individual Rate × Number of Workers × Time
3,600 = (80)(Number of Workers)(3)
Number of Workers = 15
Quantity B
Work = Individual Rate × Number of Workers × Time
4,800 = (80)(4)(Time)
Time = 15 days
The number of chefs in Quantity A is equal to the number of days in Quantity B.
