33-7r = 3(6-4r) what does r equal?

dlinn [17]

33-7r = 3(6-4r)
33 - 7r = 18 - 12r

Suppose there are two neighbors, Jared and Paul. These two neighbors have the same size lawn and the same amount of hedges. Each

Aleks04 [339]

Answer:

Paul should trim both hedges and Jared should mow both lawns.

Each neighbor would save 30 minutes per week

Step-by-step explanation:

The time each neighbor takes to finish each task is presented below:

$\begin{array}{ccc}&Paul&Jared\\Mow&120&30\\Trim&90&60\end{array}$

Jared is better at mowing the lawn than trimming hedges, while Paul is better at trimming hedges than mowing the lawn. Therefore, the two neighbors could gain by specializing and trading lawn services if Paul were to trim both hedges and Jared were to mow the lawns.

The time saved by each is:

$P = 210 -90-90=30\ min\\J = 90-30-30=30\ min$
