Stephany Douglas · Answer 1

21 % below what she needs

Step-by-step explanation:

She had hit 12, 10 and 9

This averages to

(12+10+9) / 3 = 31/3 = 10 1/3

She needs 13

Percentage = (needed-actual) / needed * 100%

= (13-10 1/3) / 13 * 100%

= (2 2/3) / 13 * 100%

=.205128205 * 100%

=20.5128205%

To the nearest whole number

21 %

She is 21 % below what she needs
