Answer:
$2.64
Step-by-step explanation:
Selling them at 5 cents each ($0.05), he could sell 1 dozen buttons for
12 * $0.05 = $0.60
As he bought them at $0.38 per dozen, the profit per dozen would be
$0.60 - $0.38 = $0.22
As 12 dozen is 1 gross, the profit per gross would be
12 * $0.22 = $2.64

Answer:

Step-by-step explanation:
Given that:
Kevin charges $10 plus $5 per hours
C = 5h + 10
To find:
The table of values for hours worked from 1 to 5.
Solution:
First of all, let us put h = 1 in the given equation:
C = 5 \times 1 + 10
C = 5 + 10 = $15
Now, let us put h = 2 in the given equation:
C = 5 \times 2 + 10
C = 10 + 10 = $20
Now, let us put h = 3 in the given equation:
C = 5 \times 3 + 10
C = 15 + 10 = $25
Now, let us put h = 4 in the given equation:
C = 5 \times 4 + 10
C = 20 + 10 = $30
Now, let us put h = 5 in the given equation:
C = 5 \times 5 + 10
C = 25 + 10 = $35
So, the table becomes each row incrementing h by 1:
