<h3>The cost of purchasing baby chicks at  $4.50 per chick represents proportional relationship</h3>

<em><u>Solution:</u></em>

in a proportional relationship, one variable is always a constant value times the other.

y = kx

Where, k is a constant

<em><u>Option 1</u></em>

The cost of purchasing hay for $26 a  bale with a delivery charge of $30

Cost = $ 26 a bale + 30

This does not forms a proportional relationship

<em><u>Option 2</u></em>

The cost of purchasing baby chicks at  $4.50 per chick

Let "x" be the number of chicks

Therefore,

cost = 4.50 \times x

Thus, this forms a proportional relationship

<em><u>Option 3</u></em>

The cost of purchasing fencing at $29  a linear foot with an installation fee of  $300

cost = $ 29 a linear foot + 300

This does not forms a proportional relationship

<em><u>Option 4</u></em>

The cost of renting a backhoe for $79  per hour with a non-refundable deposit  of $300

cost = $ 79 per hour + 300

This does not forms a proportional relationship
