I would guess that you would need to find the Least Common Multiple (LCM) of 99 and 24 first.
After listing out all of the multiples, you would have 792 be the LCM of 99 and 24. But since we need to find the integer value of n, in 99n (which means 99 x n), then we need to divide 792 by 99, which would be 8.
n = 8
answer: 360
Given:
Machine A Candy Packing
x(minutes) y(candies)
5 600
10 1200
15 1800
20 2400
Machine B : y = 150x
Find number of candies packed in 12 minutes.
Machine A : 600/5mins = 120 candies per minute
120 * 12 minutes = 1,440 candies
Machine B : y = 150x ⇒ y = 150(12) ⇒ y = 1,800
Machine B: 1,800
Machine A: 1,440
Difference 360
Machine B packed 360 more candies than Machine A in 12 minutes.
Answer:
420
Step-by-step explanation:
The number of students in the school is unknown, so we'll call it x.
55% of the number of students are girls.
There are 321 girls.
55% of x = 231
0.55x = 231
x = 231/0.55
x = 420
Answer: 420
False. 6 cannot have two y’s
