Multiply 349 by (1/10) you can use the rule: $a*(\frac{c}{d}) = \frac{a*c}{d}$

thx

5. Australopithecus

Wait

6. rainbow_rocks03

oh

7. Australopithecus

Do they define what they mean by discount rate?

8. rainbow_rocks03

huh?

9. Australopithecus

Well 1/10 is 10% so when you multiply that by 349 you get 10% of 349 so you pay 10% of the original price which seems kind of crazy Another way of interpreting it is that you get 10% off of 349 in that case you would have to subtract 1 by 1/10 then multiply by 349 1 - 1/10 gives you 90% so after multiplying you would get 10% off of 349 which seems like a more reasonable discount.

I would assume that it is 10% off the original price because paying 10% of the original price is just bonkers
