You missed one final step, no worries! When finding the percent off, subtract the value you got after dividing the price after discount by the initial price from 100.
So: 100 - 65 = 35

35% off

Hope this helps!

Please answer this correctly correctly
geniusboy [140]

Answer:

Step-by-step explanation:

+ You click on -15 for a point.

Anna buys 12 pens and 20 pencils for a total cost of $16. One pen costs $0.40 more than a pencil. What would one pencil and one
Mamont248 [21]

12x+20y=16 where x is a pen and y is a pencil. Because a pen is .40 more than a pencil we can write this in terms of pencils and extra .40:

32y+12*.4 = 16\\=32y+4.8 = 16\\=32y+4.8-4.8 = 16-4.8\\=32y = 11.2\\=32y/32 = 11.2/32\\=y = 0.35

Therefore, a pencil costs 0.35 and a pen costs 0.75. Combined, one of each costs 1.10 dollars.
