Question

Isaac bought 18 boxes of cereal. This is 30% of the total boxes at the store. How many total boxes of cereal were at the store?

Answer 1

Answer:

60

Step-by-step explanation:

30% of total boxes at the store is equal to 18

so

$(30 \div 100 ) \times x = 18 \\ x = 18 \times( 100 \div 30) = \\ 18 \times (10 \div 3) = \\ 6 \times 10 = 60$
