Question

John has saved $125 for spending money to use on a trip. His part-time job pays $15.50 per hour. He plans to use all the money he earns from the part-time job as spending money for his trip. If he works x hours at his part-time job and his trip is 5 days long, what linear function can be used to determine y, the amount of money he can spend each day of his trip?

Answer 1

125+15.50(x)=5y

If needed to be simplified

25+3.1(x)=y (Divide by 5 on both sides)

So

y=3.1x+25
