So we solve for each
70% of 100=70
students who didn't buy lunch=100-70=30
some of the 70 left so that the students who bought lunch, are 60% of those who are left
we know that the students who didn't buy lunch didn't change number so therefor
100% of students left-60%=40%= students that didn't buy lunch=30 so
40%=30
20%=15
100%=75
there were 75 students lfet in the cafeteria
X + x + 24 = 58
x = (58-24)/2=17
the first number is 17 and the second number is the sum of 17 and 28. Finding it has been left as an exercise for the reader.
Answer:
77
Step-by-step explanation:
sum of all number/total numbers
80+90+10+75+98+95+99/7
77
It is B. Because the formula for sequences in in the form of a+(n-1)d where a is the first number in the sequence, n is the nth term(position) and d is the difference between terms. So if a=9 and d=5 the answer is 9 + (n-1)*5
The name of the answer I put down is 15
