45 foot long hot dogs will be served if there are a total of 120 dogs served.
Solution:
Given that
Ratio of irregular hot dogs and foot long hot dogs is 5 : 3
Which means when 5 irregular hot dogs are serve, 3 foot long hot dogs are served.
Total number of dogs served = 120
To find : Number of foot long dogs served
[tex]\text { Number of foot long dogs served }=\frac{3}{5+3} \times \text { total number of dogs }[/tex]
[tex]\text { Number of foot long dogs served }=\frac{3}{5+3} \times 120=\frac{3}{8} \times 120=45[/tex]
Hence 45 foot long hot dogs will be served if there are a total of 120 dogs served.
