Answer:
4
Step-by-step explanation:
Amount spent on coffee = 70 - 39.56 = 30.44
One pound costs 7.61, how many will cost 30.44
7.61 : 1 = 30.44 : X
7.61 = 30.44/X
X = 30.44/7.61
X = 4
4 pounds
Do 70 - 39.56 = 30.44 To see how much she spent
Do 30.44 / 7.61 = 4 To see how many pounds of coffee she had bought
x=2/3 or 0.6666
x=1 is the correct answer
0 & 0
since the equation is missing the constant term the line is passing through the origin
and the line don't make any intercept on both the axes.
