Alandscaper estimates that a set of plants can be installed in 6 hours by 12 workers. the landscaper wants to finish a set of plants in 4 hours. assuming that the variables are inversely related, how many workers should the landscaper bring to the job?

18 workers  should the landscaper bring to the job  to finish a set of plants in 4 hours.

Step-by-step explanation:

As given

Assuming that  a set of plants can be installed in number of hours inversely related to the number of workers.

Let us assume that the number of hours needed for set up a plant be x.

Let us assume that the number of worker needed for setup a plant be y.

Thus

Where k is the constant of proportionality.

As given

A landscaper estimates that a set of plants can be installed in 6 hours by 12 workers.

x = 6 , y = 12

Thus

k = 72

As given

The landscaper wants to finish a set of plants in 4 hours.

x = 4 , k = 72

Thus

y = 18

Therefore 18 workers  should the landscaper bring to the job  to finish a set of plants in 4 hours.

isn't it a pentagon? sense [3 (triangle) + 4 (rectangle)] - 2 (triangle and rectangle connected) = 5 (pentagon)
