Question

one banana and one apple cost £0.70
how much does 1 apple cost

Answer 1

Let's assume the cost of one apple is x and the cost of one banana is y.

According to the given information, we can set up two equations:

Equation 1: 2y + x = 1.12
Equation 2: y + x = 0.70

Now, we can solve these equations to find the value of x (the cost of one apple).

To do that, let's subtract equation 2 from equation 1:
(2y + x) - (y + x) = 1.12 - 0.70
y = 0.42

So, the cost of one apple is £0.42.

Answer 2

thats wrong

Answer 3

Apologies for the mistake. Let's redo the calculation correctly.

Let's assume the cost of one apple is x and the cost of one banana is y.

According to the given information, we can set up two equations:

Equation 1: 2y + x = 1.12
Equation 2: y + x = 0.70

Now, to solve these equations, let's subtract equation 2 from equation 1:

(2y + x) - (y + x) = 1.12 - 0.70
y = 0.42

Now, let's substitute the value of y into equation 2:

0.42 + x = 0.70

Subtracting 0.42 from both sides:

x = 0.70 - 0.42
x = 0.28

Therefore, the cost of one apple is £0.28.
