Answer:

n + (8+6)

Step-by-step explanation:

"The sum of n and the sum of 8 and 6" is telling us that we are going to sum up the numbers 8 and 6  (this would be 8 + 6) and then we are going to add n

So the correct answer would be n + (8+6)

1. (n + 6)8 is incorrect because this expression tells us that we are going to sum n plus six and then we are going to multiply the result by 8.

2. n (8 + 6) is incorrect because this expression tells us that we are going to sum 8 + 6 and then we are going to multiply the result by a number n.

Therefore the correct answer is n + (8 + 6)

Your favorite craft store had a weekend sale. On the first day, all $10 items were 70% off. You bought some number of these of t
Svet_ta [14]
For the first day we have the following function:
 f (n) = (0.3 * 10) n + 8
 For the second day we have the following function:
 f (n) = (0.4 * 10) n + 5
 You spent the same amount of money as the day before:
 (0.3 * 10) n + 8 = (0.4 * 10) n + 5
 3n + 8 = 4n + 5
 n = 8-5
 n = 3 items
 We evaluate each function for n = 3
 f (3) = (0.3 * 10) * 3 + 8 = 17 $
 f (3) = (0.4 * 10) * 3 + 5 = 17 $
 The total amount of money is:
 17 + 17 = 34 $
 Answer:
 
you purchase 6 items
 
you spend at the craft store during the sale $ 34
