First you'd subtract .58 from 2.23 to get the price of the notebook.
2.23 - .58 = 1.65
(2.23×2)+1.65= 6.11
Now subtract 6.11 from ten to figure out the change amount.
10 - 6.11 = 3.89
Answer:

Step-by-step explanation:
9. For the lines 'm' and 'n' to be parallel the sum of interior angles should be 180 degrees that is:


10. For the lines 'm' and 'n' to be parallel the alternate exterior angles should be equal that is:



11. For the lines 'm' and 'n' to be parallel alternate angles should be equal that is:

Solving for 'x' we get:



12. For the lines 'm' and 'n' to be parallel corresponding angles should be equal that is:




First we want to find how much it costs for 1 stamp, so we do 8.28 divided by 18, which equals 0.46. Then, we multiply 0.46 and 12, which is 5.52. Therefore, it would cost $5.52 to buy 12 stamps.
