If construction costs are $159 000 per kilometer, find the cost of building the new road in the figure shown to the right

Step-by-step explanation:

A recipe for four batches of bread uses 5 cups of flour.

Firstly, we want to determine the number of cups of flour needed to produce one batch of bread. This means we want to determine the unit rate of producing batches of bread. It becomes

If four batches of bread uses 5 cups of flour,

Then 1 batch of bread will use x cups of flour

4x = 5

x = 5/4 = 1.25

1 batch of bread will require 1.25 cups of flour

Secondly, we want do determine how many batches of bread that can be made using 1 cup of flour. It becomes

If four batches of bread uses 5 cups of flour, then

y batches of bread will need 1 cup of flour

5y = 4

y = 4/5 = 0.8

1 cup of flour will produce 0.8 batch of bread
