Question

1. This table shows a proportional relationship between the number of ferrets and the number of foxes in prairie communities.

Ferrets Foxes
144 18
120 15
40 5
a) What is the unit rate of ferrets per foxes? Show your work.
b) Write a proportional equation that represents the relationship?

Answer 1

a) The unit rate is 8 ferrets per fox

b) y = 8x

Explanation:

`(144)/(18)` = 8

`(120)/(15)` = 8

`(40)/(5)` = 8

y = 8x

y = 8x

y = 8(18)

y = 144

y = 8x

y = 8(15)

y = 120

y = 8x

y = 8(5)

y = 40
