Question

at the grocery store, the jumbo - sized boxes of berries decreased by 20%. if the old boxes held 40 ounces of berries, how much do the new boxes hold? which point represents the unknown, the new jumbo - size boxes of berries? berries (ounces) 0 a b 40 c 0% 20% 40% 60% 80% 100% 120% b a c

Explanation:

Step1: Calculate the new amount

The old amount is 40 ounces, and it decreased by 20%. So the new percentage of the old amount is \(100\% - 20\% = 80\%\). To find the new amount, we calculate \(40\times0.8 = 32\) ounces.

Step2: Analyze the number line

Looking at the number line, the point B is at 80% (since 80% of 40 is 32, and the percentage line has B at 80%). So the point representing the new amount is B.

Answer:

B
