Answer:
New York style cheesecake: $6 Apple cheese cake: $7
Step-by-step explanation:
Ryan and Kali sold the same amount of apple cheesecakes which means the New York cheesecakes differed in amount. Ryan sold 2 more than Kali so the difference in amount would be the cost of 2 New York cheese cakes.
Ryan made $91 and Kali made $79. Since they sold the same amount of apple cheesecakes, we can use their difference in money made to find the cost of 2 New York cheesecakes. So take away 79 from 91 and you get 12. $12 is the price of 2 New York cheesecakes. So take the 12 and divide it by 2. You get 6. $6 is the price of one New York cheesecake.
To find the amount of one apple cheesecake, you just need to multiply the amount of New York cheesecakes Kali sold by the price of 1 New York cheesecake. So 6 multiplied by 12 is equal to 72. Take the money Kali made and take away 72 from it. You get 7. 7 is the cost for one apple cheesecake. $7 for 1 cheesecake.

In order to subtract 2.34 from 20, the best method is using column subtraction.
To do this, we put the main number on top, and the number we are taking away underneath it.
When we set it out, we need to make sure that all the columns line up properly, the units in one line, tens in the other etc.
If taking decimals from a whole number, I would always recommend putting '0's after the decimal point for place value.
For the layout, see below:
20.00
- 2.34
Now, as we cannot subtract 4 from 0, we must begin borrowing from the neighbours.
As 2 is the nearest number, we take one from there and move it next door
1¹0.00
Do the same again, 10 becomes 9
19.¹00
And one last time
19.9¹0
Now subtract 2.34 from 19.9¹0
19.9¹0
- 2.34
10 - 4 = 6
9 - 3 = 6
9 - 2 = 7
1 - 0 = 1
17.66

Hope it makes sense, once you get your head round it you'll be fine
Im guessing that your teacher wants you to apply the fact that no matter what order your numbers are in when adding or multiplying your outcome will be the same. So one multiplication fact is 16*147=2352 . Also if you multiply a negative times a negative you will get a positive number so -147*-16=2352 .
I hope this helps a lil:)
