The mistake that Karen made was that in order to get the 8 to switch sides, it should have been subtracted rather than added. This is because it is positive on the left side and therefore must be negative when we switch it to the right side. A proper version of this problem would be below.


y + 8 = 15

y = 15 - 8

y = 7

NNADVOKAT [17]

Answer:

3,000 people

Step-by-step explanation:

So, smaller stadium will hold  15 times less people than the larger stadium ,

Which equals , \frac{45000}{15} = 3,000 people.

Thus ,

Smaller stadium can hold a total of 3,000 people.
