Dan can tile a floor in 3 hours. his assistant could tile the same floor in 8 hours. if they work together, how long will it take to tile the floor?

There is a formula for this:

Total Time = (worker1 * worker2) / (worker1 + worker2)

(3 * 8) / (3 + 8)

24 / 11 =

2.1818181818 hours

$9.89

step-by-step explanation:

9.90 = p x .06 x .25 (3/12 changed to a decimal)

9.90 = p x 0.015

9.90 - 0.015 = p

9.89 = p

one peck is 9.309 quarts

9.309x 2
