Answer to Question #235924 in Math for John

Question

John is a door to door vacuum salesman. His weekly salary, s, is 2,000 pesos plus 50 pesos for each vacuum he sells. This can be written as S=2,000+50v, where v is the number of vacuum sold. If john earns 5000 for a weeks work, how many vacuums did he sell?

Answer 1

$$5000=2000+50v$$

$$50v=5000-2000$$

$$\dfrac{50v}{50}=\dfrac{3000}{50}$$

$$v=60$$

John sold 50 vacuums for a weeks work.
