Answer:
The answer is 54
Step-by-step explanation:
36+90=126
180-126= 54
She is incorrect cause if we take the number 20 and take 25% of it it equals 5 so now 20 is only 15. They if we take 75% away from 20 is equals 15 so then we only have 5 from 20 left. Therefore she’s incorrect because 75% leaves 5/20 and 25% leaves 15/20. Hope that makes sense.
0.06 or you can just put 6.
Basically, you have to multiply 30% x 20.
Glad I could help☺️
