If 4 out of 20 people like red jelly beans, what percent of the people do not like red jelly beans? A. 5% B. 20% C. 80% D. 90%

80%, because 4/20 expressed as a decimal is 0.2, which as a percentage is 20%.

If 20% of people like red jelly beans, that means the remainder doesn't.

100% - 20% = 80%, therefore 80% of people do not like red jelly beans.

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^
