The machine make nails at a rate of 8th pounds per hour
<h3>How to determine the rate of making machine?</h3>
From the question, the given parameters are:
- Amount of pounds of nails = 4th pounds
- Number of time = half an hour
The rate in pounds per hour the machine make nails is then calculated as
Rate of making nails = Amount of pounds of nail/Number of time
Substitute the known values in the above equation
So, we have
Rate of making nails = 4th pounds/0.5 hour
Evaluate
Rate of making nails = 8th pounds per hour
Hence, the rate of making nails is 8th pounds per hour

Answer: $12 is % of $16.
Step-by-step explanation:
STEP 1: 100 ÷ 16 = 6.25
STEP 2: <u>12 x 6.25 </u>= <u>75</u>
16 x 6.25 = 100
Now we can see that our fraction is 75/100, which means that 12/16 as a percentage is 75%.
We can also work this out in a simpler way by first converting the fraction 12/16 to a decimal. To do that, we simply divide the numerator by the denominator:
12/16 = 0.75
Once we have the answer to that division, we can multiply the answer by 100 to make it a percentage:
0.75 x 100 = 75%

Answer:
Original price = $ 280.66
New price = $319.11
Step-by-step explanation:
Let the original price be = x
Given 13.7% of original price resulted in 38.45 increase
That is,
13.7% of x = 38.45
New price is 38.45 more than original price.
That is ,
New price = 280.66 + 38.45 = $ 319.11
