The hardware store has announced a 15% discount on all household items. Having bought a can of paint, we saved 36 rubles. What is the typical paint cost?

It is known that using a 15% discount on the purchase of paint, they saved 36 rubles, i.e. 15% of the usual cost of paint is 36 rubles:

15% – 36 rubles,

100% – X rubles.

We solve using the “cross” method:

X = 36 * 100/15 = 240 rubles – the usual cost of a can of paint.
