Question

NEED HELP!!

julia and kelsey are both babysitters. julia charges a flat fee of $30 plus $5 per hour. and kelsey charges a flat fee of $10 plus $15 per hour. which system of equations represents the information given? let z represent the number of hours spent babysitting. let y represent the money earned. (answer choices are in the picture)

Answer 1

Second choice. It’s the second choice because Julia’s prices are like this: A flat fee of $30 + 5x (x representing the amount of hours). So the equation would be 30 + 5x = y (the amount she earned), and kelsey is the same. The flat fee (10) + 15x, (x representing the amount of hours), which then the equation would be 10 + 15x = y. (Y representing the amount she earned.) The equation can be in any order but it’s definitely the second choice.

Answer 2

I think it's the 2nd choice. Hopefully I got this correct :)

Explanation:

I think you wrote that z will represent the number of hours spent babysitting but I think you meant x.

It's the 2nd choice because $30 is the flat rate for Julia and $10 is the flat rate for Kelsey. Julia has a rate of $5 per hour so that will be the number with the x. And Kelsey has a rate of $15 per hour so that will be the number with the x.

Julia: y = 5x + 30

Kelsey: y = 15x + 10.
