Sagot :
Answer:
B = 25+5x
Step-by-step explanation:
B = 25+5x
Since 25 is a set price you leave it by itself, but since you don't know how many movies are ordered, you say 5x (5 times the amount ordered).
M B
1 $30 --> 25+5x1 = 30
2 $35 --> 25+5x2 = 25+10 = 35
3 $40 --> 25+5x3 = 25+15 = 40
8 $65 --> you can do that trial error method, sub in numbers in place of M
to figure out what adds up to $65. In this case it was 8
Just put that into a graph now, so put M on the x axis, and B on the y axis, and plot dots for each number, and draw a line linking the dots
Hope this helped :)
