16

Step-by-step explanation:

Given: 15% of 60 is 9.

so 9 kids are 15 year old.

and 1 other kid is 16 year old.

Thus, there are total of (15+1) kids that are either 15 or 16 year old. you can also draw venn diagram to find that.

the entire expression should be subtracted from 30. to subtract the quantity, distribute the negative sign, which changes the signs on the terms. so, the –2 changes to positive and gets added to 30 instead of subtracted from it.

hope this ! ^w^
