Answer:

5.66 years

Step-by-step explanation:

450 x 1.025^(n) = 450 + 67.50

450 x 1.025^(n) = 517.50

1.025^(n) =(517.50 / 450)

1.025^(n) = 1.15

n = ln(1.15) / ln(1.025)

n = 5.66

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
