50 students preferred science...
Explanation:
we can consider the numbers 5 and 4 in the ratio as units
now we need to know how much each unit represent
units = 5 + 4 = 9
my sample = 90 students
each unit = 90/9 = 10 students
so each unit represents 10 students
back to the ratio
who preferred science = 5
who preferred English = 4
Number of students choose Science = 5 * 10 = 50
The pattern of the first one is multiplying x 1 x 10 x 100 x 1000 x 10000 if you want the next term multiply and one zero every time the next term is 30000
the pattern of the next one is start from january and skip one month the next term is july
First, subtract 2021-2014=7.
Multiply 8.5 x 7= 0.595.
Then, multiply 21,000 x 0.595= 12,495
A + s = 324
s = 2a
a + 2a = 324
3a = 324
a = 324/3
a = 108
s = 2a
s = 2(108)
s = 216
so there were 108 adult tickets (a) and 216 student tickets (s)
