went to the candy store last weekend and I bought a total of 10 packs of candy. I bought M&Ms for dollars 1 per pack and Twizzlers for dollar 0.50 per pack. I spent a total of dollars of 6. How many packs of M&Ms did I buy?

Number of packs of M&M s bought = N
Cost of these = N * $ 1 = $ N
Number of Twizzler packs purchased = 10 - N
Cost of these = (10 - N) * $ 0.50 = $ 5.00 - N/2
total money spent = $ 6.00 = $ N + 5.00 - N /2
=> N/2 = 1
=> N = 2
So two packs of M&M and 8 packs of Twizzlers.
Cost of these = N * $ 1 = $ N
Number of Twizzler packs purchased = 10 - N
Cost of these = (10 - N) * $ 0.50 = $ 5.00 - N/2
total money spent = $ 6.00 = $ N + 5.00 - N /2
=> N/2 = 1
=> N = 2
So two packs of M&M and 8 packs of Twizzlers.
