Can you explain how to do this in steps plz?

Kelly sells ice cream bars at the beach. In addition to a fixed salary, she earns a commission for each ice cream bar she sells. The table shows Kelly's total earnings, y, in dollars, from selling x bars of ice cream:



Ice Cream Sales and Earnings

Number of Bars Sold ( x) Total Earnings (dollars) (y)

0_______________________ 50

1 ________________________52

2 _______________________54

3 _______________________56



Which equation best shows the relationship between x and y?

y = 2x + 50

y = x + 52

y = 2x + 52

y = x + 50
