ben earns $9 per hour and $6 for each delivery he makes. he wants to earn more than $155 in an 8 hours workday.what is the least number of deliveries he must make to reach his goal？
Here's the equation we need to solve
Regular Wage + Deliveries > 155
8(9) + 6D > 155
72 + 6D > 155 subtract 72 from both sides
6D > 83 divide both sides by 6
D > 13.83
So.....he needs to make at least 14 deliveries to meet his goal
