1. At san Antonio's town plaza, number of teens planted by group of students Increased fron 1,350 in 2012 to 2,175 in 2013 . What was the rate of increase is Number of teens?

To find the rate of increase in the number of teens from 2012 to 2013, you can use the following formula: \[ \text{Rate of Increase} = \frac{\text{New Value} - \text{Old Value}}{\text{Old Value}} \times 100 \] In this case: - Old Value (2012) = 1,350 - New Value (2013) = 2,175 Now, plug in the values: \[ \text{Rate of Increase} = \frac{2,175 - 1,350}{1,350} \times 100 \] Calculating the difference: \[ 2,175 - 1,350 = 825 \] Now, substitute back into the formula: \[ \text{Rate of Increase} = \frac{825}{1,350} \times 100 \] Calculating the fraction: \[ \frac{825}{1,350} \approx 0.6111 \] Now, multiply by 100 to get the percentage: \[ 0.6111 \times 100 \approx 61.11\% \] So, the rate of increase in the number of teens from 2012 to 2013 was approximately **61.11%**.
