6-77.

Two employees of Richard’s Planters can build $40$ planters in three days. At the same rate, how many employees would be needed to build $60$ planters in one day?

To find the rate, divide the number of planters by the time it takes to build the planters.

$\text{Rate}=\frac{\text{Number of Planters}}{\text{Time}}$

Since there were two original employees, you must divide the rate you found by $2$ in order to find the number of planters that $1$ employee can make in $1$ day.

Let$x =$ the number of employees.
Create an equation such that:
Planters = (Number of Employees)(Rate)

Solve for $x$.

$\text{Rate}=\frac{40}{3}=13.33$

$13.33 ÷ 2 = 6.665$ planters per day per employee

$60 = x\left(6.665\right)$

$9$ employees
