Dla członkiń zespołu tanecznego planowano kupić jednakowe spódnice po 60 zł każda.
Gdy sprzedawca obniżył cenę tych spódnic o 20%, wówczas za tę samą kwotę można było kupić o 5 spódnic więcej. Ile można było kupić spódnic po obniżonej cenie?

25

Step-by-step explanation:

Let's say x is the number of skirts, and C is the cost.  At 60 zł per skirt, the cost is:

C = 60x

When the price is reduced by 20%, the price of each skirt becomes 0.80 (60 zł) = 48 zł.  At this new price, the team can buy x+5 skirts at the same cost.

C = 48(x + 5)

Setting the expressions equal and solving for x:

60x = 48(x + 5)

60x = 48x + 240

12x = 240

x = 20

The team could buy 20 skirts at the original price, which means they can buy 25 skirts at the reduced price.

do you mean add both of the equations together

because if you do the answer is 10x-5

step-by-step explanation:

points are handed out whenever you post answers.

brainliest answers are handed out by the person asking the question, so whether your answer is picked depends entirely on whether the asker bothers to pick

if you're asking about your rank, it depends on having a certain number of points and a certain number of brainliest answers. for example, at the time of this writing, i have 44338 points out of 15000 needed for the next (nearly triple the requirement! ) but i only have 24 out of 50 required brainliest answers. this number decays, meaning after a certain amount of time (i think about a month), the total number of brainliest answers you've earned doesn't count toward this total. (i've been stuck at the same rank for a long

the lesson to learn here is that you shouldn't worry about points or rank. chances are, no matter how good an answer you may provide, your efforts will go mostly unnoticed unless you focus on the newest/most active questions that get posted.
