A valet makes $53 each day he works and approximately $7 in tips for each car he parks. if he wants to make at least $186 in one day, at least how many cars does he need to park?

Respuesta :

Answer:

19 Cars

Step-by-step explanation:

Write a linear equation:

y=7x+53

Y = Total money

X = cars parked

If we want to earn 186 dollars a day then sub y for 186 and solve x:

186=7x+53

186-53=7x

133=7x

7x=133

x=133/7

x=19

This means that he will need to park 19 cars a day to earn a total of 186 dollars in one day.
