Answer: A notebook cost $2.25
A pen cost $3.50
Step-by-step explanation:
Let the price of notebook be n
Let the price of pens be p.
Cameron buys 4 notebooks and 2 packages of pens for $16. This will be:
4n + 2p = 16 ..... equation i
Olivia buys 5 notebooks and 1 package of pens for $14.75. This will be:
5n + p = 14.75 ..... equation ii
Combining both equations will give us:
4n + 2p = 16 ..... i
5n + p = 14.75 ...... ii
Multiply equation i by 1
Multiply equation ii by 2
4n + 2p = 16 ....... iii
10n + 2p = 29.50 ...... iv
Subtract equation iii from iv
6n = 13.50
n = 13.50/6
n = 2.25
A notebook cost $2.25
Since 4n + 2p = 16 from equation I
4n + 2p = 16
4(2.25) + 2p = 16
9 + 2p = 16
2p = 16 - 9
2p = 7
p = 7/2
p = 3.5
A pen cost $3.50
Ok!
Lets find out how much he makes per month.
You do this by dividing 612 and 3. so 612 / 3 = 204.
Max makes 204 per month.
2. Now that you have the per month, you multiply it by 12.
204 x 12 = 2448
Answer: 2,448

Answer:
A proof is basically evidence from theorms, when you said given it doesn't make sense because what evidence is supporting your saying, does it physically say that this number equals this.
Study the theorms that you learned and maybe you'll find it.
