A= 0.5, B=2.2, C=0.12, D=.0.9.
Step-by-step explanation:
From a reliable source, the maximum capacity of a standard bus used as school bus is 72 students. Because the bus that Mr. Tuttle drives is already 3/4 full, only 1/4 of the capacity is unoccupied. With this, the number of the empty seats is calculated by multiplying 72 by 1/4 as shown below.
empty seats = (1/4)(72) = 18
Therefore, the bus could have accommodated 18 more students.
<C = 180 - 32
<C = 148 degrees
(<C+<D = 180)
