Answer:
B
Step-by-step explanation:
Same thing but with t instead of x
If 12 is 15% of a number than you could double 12 and get 24. The reason for this is because 15%*2 is 30% so than 12*2 would be 30% of a number. So 30% of a number is 24. If you than look at the 15% again you than will want to do 12*3 and get 46 as your answer.
Answer:
250 questions
Step-by-step explanation:
65 is equal to 26% of the total number of questions so:
65 / total number of questions (x) is equivalent to 26 / 100
(65 and 26 are a fraction of the whole thing. it doesn't matter whether they go on the numerator or denominator, as long as they are either both on one or the other)
65/x = 26/100
you can simplify this into
26x = 6500
/26 /26
then you divide by 26 on both sides to isolate the variable
x = 250
Let each amount be y.
Since b bracelets were given away, it number of persons who made the amount = b.
Total = b*y
Total amount = by.
