Manuela found a great deal on pens at 3 for .99, It was such a god deal that she decided to buy two-dozen pens. How much did she pay for the pens? Please explain
1 answer:
A dozen = 12.
Two dozen = 24
Set up a proportion:
Then we need to solve for X (the amount of money she paid)
Cross multiply to get 3x = 24(.99)
3x = 23.76
x= $7.92
Or you can do it another way if you knew 3 goes into 24 8 times, so you can multiply .99x8 = $7.92

6% to find the percentage you divide 10.80$ by 180$ and get 0.06 0.06 is 6% in decimal form therefore there was 6% sales tax (sales tax is usually 6-8% so this makes sense anyway)
Please summarize the question. Thanks!
