After the game the coach bought 9 chicken meals for 5 dollars each and 15 burger meals for 6 dollars each. What percent of the total amount the coach spent was used for the chicken meals?

1 chicken meal = $5

9 chicken meals = 9 ($5) = $45

-

1 burger meal = $6

15 burger meals = 15 ($6) = $90

-

Total amount = $90+$45 = $135

-

Percent spent on chicken meals = [$40 : $135] x 100

= 0.296 x 100

= 29.6% or approximately 30%
