Fritz wants to get a job to save up money for college, he has two options:
Mr. Smith's Bakery or Samantha's Ice Cream Shop
Mr. Smith's Bakery is close to Fritz's house so he can walk to it, it pays $8.00 per hour. Samantha's Ice Cream Shop is a bit farther away so Fritz has to pay $4 for bus fare every day, the pay is $10.00 per hour.
How long would Fritz have to work at Samantha's Ice Cream Shop to get the same amount at Mr. Smith's Bakery?
In this system, x is the number of hours worked and y is the total amount earned.
Bakery: y = 8x
Ice Cream: y = 10x-4
Solve for x using substitution
8x=10x-4
2x=4
x=2, This means that it will take 2 hours of work to get the same amount of pay.
