Biff earned $45 working at happy days drive-in. he spent 1/3 of the money on gas for his car and 1/5 of it on the flowers for his girlfriend. how much money does he have left for the big date? i know what the answer is but i do not know how to show my work or explain it. show me how you got the answer you very much i will make the points on this problem go up!

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.

(2,20) means that the 2 is 2 hours and 20 is 20$. so there both 20$ for 2 hours only the same price. like it says. so, the dunk tank and the bounce house are the same price (20$) for the same amount of time (2 hours).

hope i
