Answer:
second choice
Step-by-step explanation:
The given sums ∑ have j = 1, j = 2, j = 3, j = 4, j = 5
Consider first j = 1 and substitute in the answers to see if we get the first term of the series -3
✅
2·1 - 5 = 2-5 = -3 ✅
3·1 - 6 = 3-6 = -3 ✅
❌
We see that last choice gives us as first term to be 1 not -3 so eliminate that possibility.
Consider now j = 2 and substitute in the answers to see if we get the second term of the series -1
✅
2·2 - 5 = 4-5 = -1 ✅
3·2 - 6 = 6-6 = 0 ❌
We see that third choice gives us as second term to be 0 not -1 so eliminate that possibility.
Consider now j = 3 and substitute in the answers to see if we get the third term of the series 1
❌
2·3 - 5 = 6-5 = 1 ✅
We see that first choice gives us as third term to be -1/3 not 1 so eliminate that possibility.
Now we are left with the second choice as the only possibility.
P = 10
Explanation:
Combine like terms: -0.25p = -2.5
Divide both sides: by -0.25
Solution: p = 10
Here’s the answer !Hope this helps!
Answer:
$10.88
Step-by-step explanation:
To find the selling price, we first have to find the markup price by multiplying 8 by 36 and then dividing the product by 100.
- 8 × 36 = 288
- 288 ÷ 100 = 2.88
Now, we add the markup price the cost of the book.
Therefore, the selling price is $10.88.
