A school cafeteria has 30 boxes of Wheaty Squares cereal and 20 boxes of Mighty O's cereal. Each box has the same number of ounces of cereal. Write an expression to
represent the total ounces of cereal. Then simplify it to create an equivalent expression.

50e=t

Step-by-step explanation:

Wheaty Squares = w

Mighty O's = m

ounces in each box = e

total ounces of cereal = t

w+m=30+20=50

The percentage change is -66.7%

Step-by-step explanation:

75 people to 25 people is a percentage decrease

Mathematically, this is same as;

(25-75)/75 * 100% = -50/75 * 100 = -66.67%

To the nearest tenth of a percent, the percentage change is -66.7%
