Answer:
Step-by-step explanation:
2, -3 , -8 , -13 , - 18 .............
This is an arithmetic sequence.
First term = a = 2
Common difference = Second term - first term
= -3 - 2 = -5
Nth term = a + (n - 1)*d
= 2 + (n - 1)*(-5)
= 2 + n*(-5) - 1 *(-5)
= 2 - 5n + 5
= 7 - 5n
n = 19,
19th term = 7 - 5*19
= 7 - 95
= - 88
n = 21,
21st term = 7 - 5*21
= 7 - 105
= -98
This scenario is mostly found during a store sale where they offer discounts.
Assuming: Original price = 90 ; discount rate = 25%
Discount value = Original price * discount rate
Discount value = 90 x 25% = 22.50
Since 25% is the discount, you only need to pay 75% of the original price.
Discounted Price = original price * (100-25)% = 90 x 75% = 67.50
Answer:
Step-by-step explanation:
Let
We can factor 6 to get:
This is the graph an absolute value function that opens upwards.
The vertex is at (0,9)
The range is
For m<9, the graph is always above the x-axis.
Therefore for m<9,
Based on the advertisement seen by Dazuri, the cost of each soccer ball is $22.50
<h3>How to find the cost?</h3>
The advertisement says that the original cost of the ball is $30 but there is a 25% discount.
The price of each soccer ball is therefore reduced by the 25% discount on the ball.
The amount that each soccer ball costs is therefore:
= 30 - ( 30 x 25%)
= 30 - 7.5
= $22.50
Rest of the question is:
Soccer balls on sale at a 25% discount. Prices go back to $30 in a week. Don't miss out.
