Answer:
30 students
Step-by-step explanation:
3 students = 10% of the class.
x students = 90% of the class.
(If more, less divides. Let x be the subject. Since we know 10% of the class already, we have to find the remaining 90% that is 100% - 10% = 90%.)
x = 90%/ 10% × 3 students. ( the percentage signs cancel out and so do the zero's.)
x= 9/1 × 3 students ( 9/1 is the same as 9)
x= 27 students
(To find the total, you must add the 10% of the students to the remaining 90% of the students in the class.)
Total number of students in the class = 27 students + 3 students
= 30 students

Answer:
a) 30
b) 88
c) 70
d) 16
e) 160
f) 250
Step-by-step explanation:
So the first step would be to switch the numbers around. For example A would be 15 and 50 instead of the original order of 50 and 15. You would then take the 1st number in the new arranged order (15) and multiply it by 100, then divide in that order. 1500/50 = 30.
Another example, letter B.
Step 1 - Rearrange : 22 and 25
Step 2 - Multiple by 100 = 2200
Step 3 - Divide : 2200/25 = 88
Good Luck :) Hope this helped.

A) Job Offer #1 would be better financially until job offer 2 (in 12 years) would be a better and have more income, so IMO job offer #1 would set you better off financially
B) it would take 12 years for job offer #2 to become a better offer (you can also express this in your own words if needed)
