An electrician earns 100 dollars for a project installing light fixtures. She must pay for the light fixtures herself and they cost 2 dollars and 50 cents each at the hardware store. Create an equation to represent her profit from the project. Let x represent the number of light fixtures and y represent her total profit (the amount of money she has left over after paying for the light fixtures).

y = 100 - 2.5 x is the equation that represents her total profit from the projectStep-by-step explanation:The given is:1. An electrician earns 100 dollars for a project installing light fixtures2. She must pay for the light fixtures herself and they cost 2 dollars     and 50 cents each3. x represent the number of light fixtures and y represent her    total profitHer profit is the amount of money she has left over after paying for the light fixtures∵ The cost of each light fixtures is 2 dollars and 50 cents- Let us change the cents to dollar∵ $1 = 100 cents∴ 50 cents = [tex]\frac{50}{100}=0.5[/tex] dollar∴ 2 dollars and 50 cents = $2.5 ∵ Her profit = The money she earns - The money she pays∴ The cost of each light fixtures = $2.5∵ She installs x light fixtures∴ She pays 2.5 x dollar∵ She earns $ 100 for installing x light fixtures∵ Her profit is $y∴ y = 100 - 2.5 xy = 100 - 2.5 x is the equation that represents her total profit from the projectLearn more:You can learn more about profit in brainly.com/question/11145277#LearnwithBrainly
