Answer:
the unit rate will $7.78 per square feet.
Step-by-step explanation:
We have to calculate the unit rate foe 140 for 18 ft.
We can find the rate by unitary method.
∵ 18 square feet cost is = $140
∴ 1 square feet will cost = [tex]\frac{140}{18}[/tex] = $7.78
Therefore, the unit rate will $7.78 per square feet.
The unit rate to the nearest hundredth should be $7.78.
Given that,
- There is the cost of $140 for 18 ft.
- We need to find out the unit rate.
Based on the above information, the calculation is as follows:
[tex]= \frac{\$140}{18}[/tex]
= $7.78
Therefore we can conclude that the unit rate to the nearest hundredth should be $7.78.
