Question

at the grocery store, the jumbo - sized boxes of berries decreased by 20%. if the old boxes held 15 ounces of berries, how much do the new boxes hold? youre trying to identify and label the point on the double number line that represents the old jumbo - size boxes of berries, or the original amount of berries. start by identifying what percent represents the old boxes of berries. berries (ounces) 0% 20% 40% 60% 80% 100% 120%

Explanation:

Step1: Determine the original percentage

The old boxes represent 100% of the amount, since it's the original quantity.

Step2: Find the new percentage

The amount decreased by 20%, so the new percentage is \(100\% - 20\% = 80\%\).

Step3: Calculate the new amount

First, find 20% of 15 ounces: \(0.20\times15 = 3\) ounces. Then subtract this from the original amount: \(15 - 3 = 12\) ounces. Alternatively, calculate 80% of 15 ounces: \(0.80\times15 = 12\) ounces.

Answer:

The new boxes hold 12 ounces of berries. The point on the double number line for the original amount (old boxes) is at 100% on the percentage line and 15 ounces on the ounces line, and the new amount is at 80% on the percentage line and 12 ounces on the ounces line.
