Step-by-step explanation:
Answer: one Apple costs £ 0.20, and one banana costs £ 0.60
Step-by-step explanation:
let x = the amount of apples
let y = the amount of bananas
4x + y = 1.40
7x + y = 2
this is à system of equations
simplify the top equation to y = 1.4 - 4x
now plug that into the second equation and solve
7x + 1.4 - 4x = 2
3x + 1.4 = 2
3x = 0.6
x = 0.2
that means that one Apple costs £ 0.20
plug that back into the top equation
4x + y = 1.4
4(0.2) + y = 1.4
0.8 + y = 1.4
y = 0.6
so one banana costs £ 0.60
