Answer 1

Given:

it is given that a department store is offering a promotion on candles. The promotion is "Buy 2 candles, get 40% off the 3rd Candle".

Find:

we have to find the total cost of buying 3 same candles.

Step-by-step explanation:

Let c be the cost of one candle.

Then 2c is the cost of two candles.

and, as per offer , the price of the third candle is 40% off.

if c is the price of one candle , then the cost of third candle is

c - (40% of c) = c - 0.4c = (1 - 0.4)c = 0.6c

Therefore, cost of third candle is 0.6c.

Now, the total cost of buying three same candles = 2c + 0.6c = 2.6c

Therefore, the options 2c + 0.6c and 2.6c are correct options
