Description
henry is working odd jobs and making $45 per day. before he started working he had $200. write a linear equation that models how much money he has on any given day
Explanation & Answer
Thank you for the opportunity to help you with your question! Hope your day is going well!
We know that Henry is making 45 per day, but he already had 200 dollars.
let x=days
Then y=45x+200
To know this is correct, let's look at the first couple of days
Before he started work, x=0
y=45(0)+200
y=200 (which is the exact amount he had before working, so check!)
Day 1:
y=45(1)+200
y=245 (which makes sense, since he already had 200 and we added 45 to it)
Day 2
y=45(2)+200
y=290 (which once again makes sense).
Hence this is the correct linear equation.
