Answer:
Step-by-step explanation:
If there are 75 people, we can divide this number to the capacity of each taxi to find out which taxis could be best.
Small: [tex]\frac{75}{4}=18.75[/tex], which means 19 small taxis would be needed for all of them. That costs [tex]19 \times \$40 = \$760[/tex].
Therefore, if they use small taxis, that would cost $760.
Large: [tex]\frac{75}{7} \approx 10.7[/tex], which means 11 taxis would be need for all of them. That would cost [tex]11 \times \$63 = \$693[/tex].
Therefore, if they use large taxis, that would cost $693.
Definitely, the best choice is to use large taxis, they would cost $97 less than small taxis.
