2 kg of grapes cost $6y and 2 kg of mangoes cost $28 more than 1 kg of grapes. Find the cost of 2 kg of mangoes.

Answer 1

Let the cost of 1 kg of grapes be x.

Since 2 kg of grapes cost $6y, the cost of 2 kg of grapes would be 2x = $6y.

This can be written as 2x = $6y.

Dividing by 2 on both sides, we get x = $3y.

Therefore, the cost of 1 kg of grapes is $3y.

Now, the cost of 2 kg of mangoes is $28 more than 1 kg of grapes, which is x + $28.

Substitute x = $3y into the equation, we get the cost of 2 kg of mangoes is $3y + $28 = $3y + $28.

Therefore, the cost of 2 kg of mangoes is $3y + $28.
