In february, alec had 1,513 visitors to his website. in march, he had 1,381 visitors to his website. what is the percentage decrease of the number of visitors to alec's website from february to march? if necessary, round to the nearest tenth of a percent. 91.3% 10.5% 8.7% 9.6%

Respuesta :

Subtract old value (1513) from new value (1381): 1381 - 1513 = -132
The negative tells you it is a percentage decrease...now ignore it.
Divide the amount of decrease (132) by the old value (1513): [tex] \frac{132}{1513} =0.087[/tex]
Multiply this number by 100: 0.087(100) = 8.7%
