Question

In a random sample of egg cartons, a supermarket finds that 3 cartons in every 50 cartons contain cracked eggs. If the supermarket receives a shipment of 400 cartons, how many cartons can they expect will contain cracked eggs? A. 24 cartons B. 30 cartons C. 14 cartons

Answer 1

$\frac{3}{50} =\frac{x}{400}$. Cross multiply: 1200=50x. Divide both sides by 50; therefore, x=24/A.
