Question

crunch bunch cereal boxes come in two sizes. the mini cereal box of crunch bunch is a reduction of the standard box.
what is the height of the standard size box of crunch bunch?
15.2 inches
10 inches
6.4 inches
1.6 inches

Explanation:

Step1: Set up proportion

Since the boxes are similar, the ratios of their corresponding sides are equal. So, $\frac{x}{8}=\frac{4}{3.2}$.

Step2: Solve for \(x\)

Cross - multiply: $3.2x = 4\times8$. Then $3.2x=32$. Divide both sides by $3.2$: $x=\frac{32}{3.2}=10$.

Answer:

10 inches
