Okay, so there are nickels and pennies in this jar.
So, let's call the number of pennies X
Since there are 161 coins altogether, the number of nickels is (161 - X)
So now we solve the equation:
.01X + .05(161 - X) = 3.09
.01X + 8.05 - .05X = 3. 09
4.96 = .04X
124 = X
So, there are 124 pennies
Therefore, there are 161 - 124 = 37 nickels
Let's check our answer:
124 x .01 + 37x .05 = 1.24 + 1.85 = 3.09
It works!
Reduced by 20% means it is on sale for 80% of the original price ( 100% - 20% = 80%)
Multiply the original price by 80%
36 x 0.8 = 28.80
The sale price is £28.80
The answer is d because x has to be 74 degrees and I chose the most logical one
Answer: 5
Step-by-step explanation: I got it right
The percentage of animal wasted is the number of animal wasted over 100
85.7% of the wild caught animals are wasted
<h3>How to calculate the animal wasted</h3>
From the question, we have:
Animals caught = 6 pounds
Salmon = 1 pound
The total weight in the system is:
Total = 6 pounds + 1 pound
So, we have:
Total = 7 pounds
The percent of wild caught animals wasted is then calculated as:
Simplify
Hence, 85.7% of the wild caught animals are wasted
