Answer :
Answer:
Step-by-step explanation:
Assume the cost for a cup of coffee is x and the cost for a cup of tea is y.
For Alex: 4x+3y=6.95
For Ben 5x+2y=7.20
Then multiply Alex's cost by 2 and Ben's by 3 to cancel y.
8x+6y=13.90
15x+6y=21.60
Equation 2 minus equation 1 would be
15x+6y-(8x+6y)=15x+6y-8x-6y=7x
21.60-13.90=7.70
7x=7.70
Then x=1.10 and plugging it one of the equations,
y= 0.85
A cup of coffee costs 1.10 pounds and A cup of tea is 0.85 pounds
