1. Rhianne is comparing the prices of fly fishing lures. She wrote the prices of lures in the
table below. Based on the table is the price proportional to the number of lures?
Number of
Lures
Price
(in dollars)
$2.58 6
$2.94 7
$3.28 8

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form [tex]k=\frac{y}{x}[/tex] or [tex]y=kx[/tex]

Let

y ---> the price

x ---> the number of lures

Find the constant of proportionality for each ordered pair

If all the values of k are equal then the relationship represent a proportional variation

[tex]k=\frac{y}{x}[/tex]

For (6,2.58) ----> [tex]k=\frac{2.58}{6}=0.43[/tex]

For (7,2.94) ----> [tex]k=\frac{2.94}{7}=0.42[/tex]

For (8,3.28) ----> [tex]k=\frac{3.28}{8}=0.41[/tex]

The values of k are different

therefore

The price is not proportional to the number of lures
