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)

(x) (y)
0 50
1 52
2 54
3 56

which equation best shows the relationship between x and y? (5 points)

a. y = 2x + 50

b. y = x + 52

c. y = 2x + 52

d. y = x + 50

Step-by-step explanation:

Given: The salary of Kelly is fixed but she earns a commission for each ice cream she sells.

Thus, Her earning will be a linear function dependent upon the number of bars she sold.

Since y represents the total earning of Kelly on selling x bars of ice- cream.

We can see at x=0, y=50

Thus her fixed salary=$50

Then, , where m is the commission she gets for each ice cream.

Also at x=1, y=52.....> put thus in above equation

Then,

hence, the equation best shows the relationship between x and y is :-
