Four cups of tea and two cups of coffee cost £3.90. Two cups of tea and three cups of coffee cost £3.45.
What's the cost of tea? What's the cost of coffee?

answer:

c. the third graph

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

eventually after a few more steps, your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x

the answer to your question is b.
