Question

Sarah is saving money to go on a trip. She needs at least $1975 in order to go. Sarah is mowing lawns and walking dogs to raise money. She charges $25 each time he mows a lawn and $15 each time she walks a dog. I have to Define the variables for the problem and Write an inequality to model this problem

Answer 1

We're told from the question that Sarah needs atleast $1975, that means that she can either have exactly $1975 or more but not less;

Let x represent the number times she mows a lawn;

Let y represent the number of times she walks a dog;

The inequality can be modelled thus;

`25x+15y\ge1975`
