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. And the options are $(2y plus 28) and $(6y plus 28) and $(5y/2 plus 14) and $(6y/2 plus 28)

1 answer

Let the cost of 1 kg of grapes be x. So, the cost of 2 kg of grapes is 2x which is equal to $6y.

Therefore, x = $3y

Now, the cost of 2 kg of mangoes is $28 more than the cost of 1 kg of grapes. Since 1 kg of grapes costs $3y, 2 kg of grapes will cost $6y. Therefore, the cost of 2 kg of mangoes is $6y + $28 = $(6y + 28).

So, the correct option is $(6y + 28).
