Answer 1

The correct option is C)
`d= 1.5p`

Explanation:

Consider the provided information.

A farmer charges $6 for 4 pounds of tomatoes.

First find the unit rate as shown below:

`(6)/(4)=1.5`

Therefore, the cost of 1 pound of tomatoes is $1.5

let d represents the dollars he should charge and p represent the pounds of tomatoes farmer sold.

Thus the required equation is
`d=1.5p`

Hence, the correct option is C)
`d= 1.5p`
