Question 1096024: A supermarket puts candies on sale. For the first 5 packets the price is $2 less than the original price of "n" dollars per packet, and for the next 5 packets the price is $1 less than the original price. There is no reduction in price for the number in excess of 10 packets. If Rick bought 12 packets, how much money in dollars will he pay?
This is what I tried:
For the first 5 packets, deduct $10 from original price
For the next 5 packets, deduct $5 from original price
For the next 2 packets, no deduction
So, 12p = n - 15 and then I have no idea on what to do. Please help.
