A shop sells mangoes at a price of

x

dollars per kg. During a promotion, the price is reduced by \$3 per kg. With \80, Ali can buy 4 kg more mangoes during the promotion than before.

Using this information, form an equation in

x

and simplify it to show that it becomes

x^2 - 3x - 135 = 0

$x^2 - 3x - 135 = 0$
$x^2 + 3x - 135 = 0$
$x^2 - 3x + 135 = 0$
$x^2 + 3x + 135 = 0$
