Afurniture store is having a sale on couches. if a couch that originally costs $3400 is on sale for 15% off, what is the actual cost of the couch?

To solve this one we need to find 15% of 3400 and then subtract it from 3400

to find percent we multiply so we'll multiply by 0.15

3400 times 0.15=510

3400-510=2890

then actual cost of the couch is $2890

I hope I've helped!

The first one, i believe, would be correct. all the others have one thing in common, and that's that they have repeating numbers. in the second one, x and y have repeating 6's and 3's, and in the third, x and y have repeating 6's as well. in the last one, there are repeating 3's. the first one has no repeating numbers.
