Hello from MrBillDoesMath!
Answer:
Choice B, 24 adults
Discussion:
From the attachment we see that 4 buses are full (they hold 4 * 40 = 160 passengers as each bus can hold 40 people) and the 5th or last bus was 4/5 full. That means the 5th bus had 4/5(40) = 160/5 = 32 passengers. So the total number of passengers on all buses is
(4 * 40) + 32 = 192
Since 1/8 of all passengers are adults, (1/8) 192, or 24, passengers are adults. This is Choice B
Thank you,
MrB
8/24= b/12
The denominator in the first fraction is 2 times greater than the denominator in the second fraction. Thus, this must be the case for the numerators.
b=8/2=4
For this case we have the following equation:
From here, we must clear the value of c.
We have then:
Rewriting we have:
Answer:
The value of c is given by:
Option B.

Here, the given expression is:
Now to simplify the given expression, perform operations on LIKE TERMS:
We get:
Hence the simplified form of the given expression is
Michael must've rounded 500 to 600, and 754 to 800, which means there's an approximate difference of 200 between their scores.
