Question

Hector can buy a banana and a tomato for 56 cents. He can buy a peach and a banana for 51 cents or he can buy a tomato and a peach for 69 cents. How much does a banana cost?

Answer 1

Explanation:

Let us represent:

Banana = b

Tomato = t

Peach = p

Hector can buy a banana and a tomato for 56 cents.

b + t = 56

b = 56 - t

He can buy a peach and a banana for 51 cents

p + b = 51

or

He can buy a tomato and a peach for 69 cents.

t + p = 69

p = 69 - t

p + b = 51

69 - t + b = 51
