Answer: y=2x+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, y=mx+50, where m is the commission she gets for each ice cream.

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

Then, 52=m(1)+50\\\Rightarrow\ m=52-50\\\Rightarrow\ m=2

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

y=2x+50

Reva is playing a bean-bag toss game. For each bag that misses the board, the player scores -8 points. Reva misses the board 4 t
erica [24]

Answer:

The answer is -32.

Step-by-step explanation:

Since there is no detailed information given about the game or the total tosses in the question, i will assume that the game is concluded when each player has had 4 tosses.

Considering the information that Reva missed the board 4 times out of her total 4 tosses in the game and each miss results in -8 points, her total score for those 4 tosses should be -8x4 = -32.

I hope this answer helps.
