I am stuck on this /(ㄒoㄒ)/~~ A push-cart vendor is selling sodas at the beach. Partway into the day, he raises his price per bottle by one quarter. After this price increase, the total dollar amount collected for the day after selling n bottles at the new price is given by the following equation:
T = 12 + 1.75n

According to this equation, how many bottles did the vendor sell today before raising the price?

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.
