6. In 2020 , summer camp registration was \( \$ 15 \) more than it was in 2021 . In 2020 , registration was \( \$ 285 \). By what percentage did the summer camp registration decrease in 2021 ?

To find the percentage decrease in summer camp registration from 2020 to 2021, we first need to determine the registration cost in 2021. Given: - Registration cost in 2020 = $285 - Registration cost in 2021 = $285 - $15 = $270 Now, we can calculate the percentage decrease in registration cost from 2020 to 2021. Percentage decrease = ((Registration cost in 2020 - Registration cost in 2021) / Registration cost in 2020) * 100 Substitute the values: Percentage decrease = ((285 - 270) / 285) * 100 Calculate the percentage decrease. Calculate the value by following steps: - step0: Calculate: \(\frac{\left(285-270\right)}{285}\times 100\) - step1: Remove the parentheses: \(\frac{285-270}{285}\times 100\) - step2: Subtract the numbers: \(\frac{15}{285}\times 100\) - step3: Reduce the fraction: \(\frac{1}{19}\times 100\) - step4: Multiply: \(\frac{100}{19}\) The percentage decrease in summer camp registration from 2020 to 2021 is approximately 5.26%.
