It’s 25.5 because since 25 off of 100 equals 75, you times the 34 by .75
264/2200 = 0.12
0.12*100 = 12%
Answer:
A is 6
B is 9.4
Step-by-step explanation:
First you put the numbers in order. then you take the middle number of the data set. This is how you find the median. For the mean you add all of the number in the data set then divide by how many numbers are there
So n=number of nickles
d=number of dimes
n is 12 more than d so
n=12+d
but they have same amount of money so
n times 5=worth of nickles
d times 10=worth of dimes
5n=10d
divide both sides by 5
n=2d
subsitute
n=2d
n=12+d
2d=n=12+d
2d=12+d
subtract d from both sides
d=12
subsitute
n=12+d
n=12+12
n=24
24 nickles
12 dimes
