Question 5 - Price Graphs
Comparing price quotes: Oren vs. Tomer
Progress: 0 out of 5 questions
x Price (NIS) Area (sq m) 0 200 400 600 800 1000 1200 1400 5 10 15 20 25 30 35 40 I II 17
Graph I
Graph II
Intersection point
Given:
Oren: Price = 700 + 20x
Tomer: Price = 48x
(x = area in sq m, Price = price in NIS)
a
Which graph belongs to each tiler?
Graph I belongs to:
Correct! Graph I passes through the origin
Graph II belongs to:
Correct! Graph II starts at 700
b1
For what area is the price the same for both?
sq m
Correct! Exactly at the intersection point
b2
What is the price for that area?
NIS
Excellent! 48 x 25 = 1200 NIS
c1
For an area of 17 sq m - who is cheaper?
Correct! Tomer: 816 NIS, Oren: 1040 NIS
c2
By how much is he cheaper?
NIS
Great! 1040 - 816 = 224 NIS

Well done! You completed all the questions!

You learned to identify graphs by their formulas and calculate intersection points!
