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
6, 8, 3, 10 will be the answer for this question
The answer is 2300

Step-by-step explanation:
Answer:
(-5, 4]
Step-by-step explanation:
Range is the set of possible outputs for a function within the given domain. It is usually represented in terms of minimum and max values
In the graph, the minimum value is -5 (not including this value) and this occurs at x = 3; the max value is 4 at x = 0
So range is -5 < x ≤ 4
which in interval notation is
(-5, 4]
