Answer:
216 muffins were ordered
Step-by-step explanation:
81/x = 37.5%/100%
divide 37.5 by 100
81/x = .375
multiply x to both sides
×(x)= ×(x)
81 = .375x
divide both sides by .375
÷.375 = ÷.375
216 = x
x = 216
x = 216
When you add integers, you keep the sign on the sum.
For example:
-9 + -9 = -18 (kept the sign)
9 + 9 = 18 (kept the "sign")
