Answer: A
n-4(32.5) > 300;n > 430tep-by-step explanation:
given that Zack wants to make a profit of more than $300 for painting 4 identical rooms. That is
Profit > $300
Then, the profit he makes is equal to the amount he is paid minus the cost of supplies. The cost of supplies is $32.50 for each room. That is
n - 32.5 and
P + 32.5 × 4
Where 4 = number of rooms
P + 130
The minimum profit = 300 + 130 = $430
Therefore, the inequality and solution that represent the dollar amount, n, that zack must be paid for each room if he is to make a profit of more than 300$ is
n-4(32.5) > 300;n > 430
Since the number of bird decreases 3% per year then for year 1 there will be 29 100 birds left. This value is 97% of 30000. From this the number of birds for year 1 is N = 30000(1-0.03)
A. N = 30,000

B. To solve this we use the equation we established in letter A. We get the answer by substituting T with 20. N = 16,000. <span />
Answer: 
Step-by-step explanation:
You know that:
- 2/5 of the spice mixture was oregano.
- 1/3 of the spice mixture was basil.
Then, to find the fraction of the total amount of spice mixture that was oregano and basil, you must add both fractions, as following:
- Find the least common multiply of the denominators:

- Divide the LCM by each original denominator and multiply the result by each numerator.
- Make the addition.
Then, the result is:

Answer: The regular price of the granola bars were $5 each.
Step-by-step explanation:
Hi, to answer this question we have to write an equation with the information given:
- <em>Discount = 10% = 0.10 (decimal form, 10/100 =0.1)
</em>
- <em>Cost after discount: $4.50
</em>
So, the original price of the granola bar (x) multiplied by 0.9 ( since 100% is the full price,1- 0.1= 0.9) equals to 4.50 (cost after discount)
Mathematically speaking
x (1- 0.1) = 4.50
x 0.9 =4.50
x = 4.50/0.9
x= 5
