Question

A store sells rope by the meter. The equation p=0.75L represents the price p(in dollars) of a piece of nylon rope that is L meters long.
A. How much does the nylon cost per meter?

B. How long is a piece of nylon rope that costs $1.50. Meters long.

Answer 1

Answer:

p=0.75L (General equation)

A. When L=1m

p=0.75×1

p=$0.75

B. When p=$1.50

Substituting p into the general equation;

1.50=0.75L

L=1.50/0.75

L=2m
