Question

sunnys surf shop sold 160 surfboards this week, which was 320 percent of the number of surfboards sold last week. how many surfboards did sunnys surf shop sell last week? 16 50 160 512

Explanation:

Step1: Define the variable

Let \( x \) be the number of surfboards sold last week.

Step2: Set up the equation

We know that 160 is 320% of \( x \). In mathematical terms, \( 160 = 3.2x \) (since 320% = 3.2).

Step3: Solve for \( x \)

To find \( x \), we divide both sides of the equation by 3.2: \( x=\frac{160}{3.2} = 50 \).

Answer:

50 (corresponding to the option "50")
