Answer 1

see below

Explanation:

Proportion:

4.41 is to 3 erasers as 'x' is to 4 erasers:

4.41 /3 = x / 4 <======this is your proportion

or rearrange

4 * 4.41/3 = x

(this results in x = $ 5.88 for 4 erasers )

Answer 2

$5.88

Explanation:

3 erasers ⇒ $4,41

4 erasers ⇒ $A

A = 4 erasers * $4.41 / 3 erasers

A = $ 5.88
