Answer:

There are 8 quarters in the jar.

Step-by-step explanation:

There are 20 coins in a jar.

Each coin is either a nickel or a quarter.

The probability of selecting a nickel is 0.6

Let's assume there are x number of nickels

The probability of selecting a nickel coin is $\frac{x}{20}$ = 0.6

So x = 0.6 × 20 = 12

Hence there are are 12 nickel coins and 20 - 12 = 8 quarter coins.

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.
