I'm not sure how you got your answer, but you should start by adding up all the expenses:

Newspaper $2250 Television $1425
Radio $954 Yellow Pages $1605
Outdoor $1950 Miscellaneous $2775

Total = $10959

Next, divide the radio expense by the total expenses:
954%2F10959=+0.0870517383

Finally, convert this decimal to a percent by moving the decimal two places to the right, and round to the nearest tenth:
0.0870517383 = 08.70517383% which rounds off to 8.7%
