There are 4 3-passenger taxis available so that's 4 x 3 = 12 total seats. There are 15 people needing transportation leaving 15 - 12 = 3 who will have to find other transportation.

Calculate the number of vans needed by dividing the number of people that need transported by the capacity of one van:

vans = \( \frac{88}{9} \) = 9\(\frac{7}{9}\)

So, it will take 9 full vans and one partially full van to transport the entire team making a total of 10 vans.

Average speed in miles per hour is the number of miles traveled divided by the number of hours:

Solving for distance:

distance = \( \text{speed} \times \text{time} \)
distance = \( 35mph \times 8h \)
280 miles

To add or subtract terms with exponents, both the base and the exponent must be the same. In this case they are so subtract the coefficients and retain the base and exponent:

9x² - 5x²
(9 - 5)x²
4x²

If the tiger has consumed 44 pounds of food in 4 days that's \( \frac{44}{4} \) = 11 pounds of food per day. The tiger needs to consume 121 - 44 = 77 more pounds of food to reach 121 pounds total. At 11 pounds of food per day that's \( \frac{77}{11} \) = 7 more days.
