Question

A store sells rope by the meter. The equation p = .8 L represents the price: p (in dollars) of a piece of nylon rope that is L meters long.

How long is a piece of nylon rope that is $2.80?

Answer 1

3.5 meters

Explanation:

Equation: p = 0.8L

Given: p = 2.80

To find the length of a piece of nylon rope that costs $2.80, input the given value of p(2.80) into the equation and solve for L:

p = 0.8L

2.8 = 0.8L

Divide both sides by .8 to isolate L:

`(2.8)/(0.8) =(0.8L)/(0.8)`

3.5 = L

The length of a piece of nylon rope that costs $2.80 is 3.5 meters long.
