Final answer:
The percent decrease in the number of smoothies from 2,600 to 2,080 is calculated by finding the absolute decrease, dividing by the initial amount, and then converting to a percentage. The calculations reveal a 20% decrease.
Step-by-step explanation:
To calculate the percent decrease in the number of smoothies from 2,600 to 2,080, we can use the following steps:
- Find the absolute decrease by subtracting the final amount from the initial amount: 2,600 - 2,080 = 520.
- Divide the absolute decrease by the initial amount to find the proportional decrease: 520 ÷ 2,600.
- Multiply the result by 100 to find the percent decrease: (520 ÷ 2,600) × 100.
Carrying out the calculations: (520 ÷ 2,600) × 100 = 0.2 × 100 = 20%. Therefore, the number of smoothies decreased by 20 percent.
