If 110 students play both
The 300 that play volleyball includes them.
That’s mean that 190 (300-110) play only volleyball
Also (the same) 200 play cricket, so only cricket play 90 students (200-110)

(300-110)+(200-110) = 190+ 90 = 280
Answer: 280
Penny- 3g
nickel-5g
dime- 2g
quarter-6g
half dollar- 11g
Your equation would be:
12x = $180
In solving for x, you need to divide 12 by 180 to get x by itself
180 divided by 12 = x
x = 15
