188 hot dogs are needed in question 5.
Company A)
[tex]\frac{188}{25}=7.52\approx8[/tex]
Thus, the total cost would be
[tex]\Rightarrow A=15\cdot8+65=185[/tex]
$185.
Company B)
[tex]\frac{188}{14}=13.4285\ldots\approx14[/tex]
Therefore, the total cost would be $160
[tex]B=7\cdot14+62=160[/tex]
Company C)
[tex]\frac{188}{50}=3.76\approx4[/tex]
The total cost would be $145
[tex]C=22\cdot4+57=145[/tex]
Thus, company C will charge you the least amount of money
