The points in the graph are (-1,0) and (3,0). I solved the equation using the Factoring method in solving quadratic equations. As I solved for finding x= -1 and 3, I substituted both to the equation in order to find y.
Answer: No. Pennant Sports Shop did not sell the same ratio of defense sticks to total lacrosse sticks on both days.
Step-by-step explanation:
On Friday, there were 25 lacrosse sticks sold, 10 of which were defense sticks. The ratio of defense sticks to lacrosse will be:
= 10/25 = 2/5 = 2:5
On Saturday, there were 50 lacrosse sticks sold, 15 of which were defense stick. The ratio of defense sticks to lacrosse will be:
= 15/50 = 3/10 = 3:10
Based on the calculation above, Pennant Sports Shop did not sell the same ratio of defense sticks to total lacrosse sticks on both days
Answer:
- It has been paid $ 1,246.10 into interest (option b.)
Explanation:
The amount <em>paid into interest</em> is the sum of the interest paid every month, but since the<em> table shows </em>only the interest paid month 17 through month 25, you should find snother way to calculate this amount.
You can do it by realizing that the total payments accumlated after 2 years equal the total amount paid to the principal plus the total amount paid into interest during that time.
Since the payments are constant, you can assert that after two years, i.e. 24 months, the total amount paid is the product of the number of payments by the amount of each payment:
- Total payments = 24 × $ 371.13 = $ 8,907.12
You can know the amount that has gone to principal by subtracting the balance at month 24 ($ 4,278.98) from the loan amount ($11,970.00):
- Payments against principal = $ 11,970.00 - $ 4,278.98 = $ 7,661.02
The payments to interest are the total payments less the payments against the principal:
- Payments to interest = $ 8,907.12 - $ 7,661.02 = $ 1,246.10
