Remember that a percentage means "parts out of 100". 24% in decimal form is therefore 0.24, because it is 24 out of the possible 100, or 1.0. To find 24% of 75, you just multiply 0.24 times 75:
75 x 0.24 = 18
Answer:
The answer for this question is 5
-x-x+7 would be equivalent
Formula is
d = d(10^k+p - 10^k) / 10^k+p - 10^k
where d = the decimal;
k = number of the non repeating decimal digits; which in this case is one
p = repeating decimal digits which in this case is one
Final Answer for this question after simplifying is 5/18
Let x is the amount of $11 per pound coffee
then the equation will be,
11x + 3(30) = 5 (x + 30)
11x + 90 = 5x + 150
11x - 5x = 150 - 90
6x = 60
x = 10
So, $10 is the amount of $11 per coffee that should be added
