Respuesta :
Clare's height increased by about 7.4% in the last year
Solution:
One year ago clare was 4 feet and 6 inches tall
Now clare is 4 feet and 10 inches tall
Convert to inches
1 feet = 12 inches
4 feet and 6 inches = (4 x 12) + 6 inches = 54 inches
4 feet and 10 inches = (4 x 12) + 10 inches = 58 inches
Formula for Percent of Increase:
[tex]Percent\ Increase = \frac{\text{Final value - initial value}}{initial\ value} \times 100[/tex]
Here,
Initial value = 54 inches
Final value = 58 inches
Substituting the values we get,
[tex]Percent\ Increase = \frac{58-54}{54} \times 100\\\\Percent\ Increase = \frac{4}{54} \times 100\\\\Percent\ Increase = 7.4074 \approx 7.4[/tex]
Thus percent increase is 7.4 %
