Dear VP helper,
I've confused about this question:
"7.Mario saved more than $30 when buying his TV at a 15% discount.what is the least expensive price that the TV could have cost before the discount?"
the given key of the book is followed:
"Mario's savings,15% off of the retail price,are more than $30.We can write this mathematically as:
15% of retail> 30
15/100 R >30
I thought the answer is
15% off of the retail >30
85% of retail >30
85% R >30
Am I miss something? What do you think of this question?
Thanks,have a nice day!
