Answer:
1966600 items must be produced in other to profit $3933
Step-by-step explanation:
from the equation y = 0.002x -0.20
where y is the profit in dollars
and x is the number of items
then to get the number of item to be produced in other to profit $3933 ?
will be by substituting $3933 for y in the equation and solving for x,
3933 = 0.002x - 0.20
Firstly you will add 0.20 to both sides, which will be
3933 + 0.20 = 0.002x - 0.20 + 0.20
3933.20 = 0.002x
then we will divide both sides by 0.002
3933.20 / 0.002 = 0.002x / 0.002
therefore, x = 1966600

Let's figure out how long it would take 1 person to dig the hole and then divide that number by 9 (since they are sharing the workload).
