A total of 316 adults and children went to a bird park. There were 44 more children than adults at the bird park. Given that the number of girls was 3 times the number of boys at the bird park, how many girls were at the bird park?
Adults |

4 u - 44 |
4 u |
316 |

Girls |
Boys |

3 u |
1 u |

Number of boys = 1 u
Number of girls = 3 u
Number of children = 1 u + 3 u = 4 u
Number of adults = 4 u - 44
Total number of people
= 4 u + 4 u - 44
= 8 u - 44
8 u - 44 = 316
8 u = 316 + 44
8 u = 360
1 u = 360 ÷ 8 = 45
Number of girls
= 3 u
= 3 x 45
= 135
Answer(s): 135
