Answer: Lucy will have a total of $56.15 left after buying the E-Book.
Step-by-step explanation:
To find the answer, you will need to add together the total amount of money Lucy received from every one for her birthday.
After getting the total by using addition, you will need to use subtraction to get the answer for the total remaining money.
$20.00 + $15.00 + $32.00 = $67.00
$67.00 - $10.85 = $56.15

Step-by-step explanation:
If you start with 1 cheerleader in row A, then you'll have 3 cheerleaders in row B (add on 2), and then 5 cheerleaders for row C (add on another 2), etc etc.
Note how: 1+3+5 = 4+5 = 9 which is a perfect square. Also note that 36 is a perfect square.
Rule: The sum of the first positive n odd numbers is going to be equal to n^2. In the example of adding the first three odd numbers (1,3,5), we have n^2 = 3^2 = 9 as the sum
So as you can see, we'll have n = 6 rows because n^2 = 6^2 = 36 and
1+3+5+7+9+11 = 36
which is the sum of the first six positive odd numbers. So we'll have 1 cheerleader in row A, 3 in row B, 5 in row C, 7 in row D, 9 in row E, 11 in row F to have 6 rows total.
To determine the number of rows in the triangular formation, set up an equation and solve for x. The number of rows is 6.
To determine the number of rows in the triangular formation, we can set up a series of equations.
Let x be the number of rows.
The first row will have 1 cheerleader, the second row will have 3 cheerleaders, the third row will have 5 cheerleaders, and so on.
We can set up the equation: 1 + 3 + 5 + ... + (2x-1) = 36.
This is the sum of an arithmetic sequence with a common difference of 2. Solving for x, we get x = 6.
Therefore, there will be 6 rows in the formation.

Answer:
$49
Step-by-step explanation:
We have been given that Eric bought lunch for him and his friends at Papa's Pizza. His bill was $50 with tax. If he used a 15% off coupon and then left a 20% tip based on the discounted ticket.
First of all, we will find amount of bill after 15% discount by finding 85% of $50 as:
Amount paid in tip would be 20% of $42.5, so total amount paid after 20% tip would be 42.5 plus 20% of $42.5.
Now, we will subtract $51 from $100 to find amount of change that is
Therefore, Eric will get $49 in change.
Answer:
49
Step-by-step explanation:
50*0.85 (15% off) = 42.5, 42.5*1.20 (20% tip) = 51, 100-51 = 49
