A city bus has five stops left on its route. At the first stop, people get off. At the second stop,
get off. At the third, no one gets off. At the fourth,
people get off. At the fifth, there are
people left on the bus, and they all get off. How many people were on the bus before the first stop?
Explanation
To solve, create a linear equation:
represents the total number of people on the bus before the first stop.
We then subtract the amount of people that got off at each stop and set that equal to the number of people to get off at the final stop.

What is the solution of the above equation?
Explanation
We can show this using objects:
We can see that only 7 objects are left.

For the following questions, please select the answer that most correctly completes the equation.
Explanation
Ones digit:
Tens digit: (leave the two at the tens, carry the one to the hundreds digit)
Hundreds digit: , add the one from the tens digit, so you get 5 + 1 = 6
Thousands digit:
Explanation

Start with . That gives
. Write the ones' place down underneath the
and the
and carry the
to the next place.
Next, do . That gives
. However, remember to add the
you carried over from the previous step.
Now, write down down next to the
. Make sure the
is lined up beneath the
and
and the
is in the hundreds' place.
Now, do . Because we are multiplying using the tens' place of
, you need to make sure that you write down the product of
and
in the tens' place, underneath the
from your previous answer.
Next, do . Write this product (
) in the hundreds' place.
Finally, add these two numbers together.

Round to the nearest ones' place.
Explanation
To figure out how to round the ones' place, we need to first look at the digit that's to the right of it. If the digit to the right of the ones' place is less than 5, then we leave the ones' place alone.
Since the tenths place is 1, we will leave the ones place alone.
