2:
The local bank charges a monthly
service charge of $3.50 plus 8 cents for each check.
In the month of October, Mike's total charges were
$5.58. How many checks did he write?
- 30 checks
- 26 checks
- 18 checks
- 42 checks

Begin with
the 6 steps mentioned above on how to help solve
math problems.
-
Step
1: Understand the problem,
what is being asked of you with this problem?
You are asked to find the number checks Mike
wrote during the month of October.
-
Step
2: Next, analyze the information
you are given. You know that Mike pays $3.50
a month for writing checks and also pays 8 cents
for each check written. You also know that his
total charges were $5.58.
-
Step
3: Plan your strategy on how
to solve this problem. You will want to solve
this one with a couple of different steps. First,
find out the difference between $5.58 and $3.50
so you can see how much was paid for writing
each check after the service charge. Then find
out how many times 8 cents goes into that difference.
That will tell you the number of checks Mike
wrote.
-
Step
4: As we look over the sentence,
you estimate the answer to be around
30. See how close your estimate is by going
to step 5.
-
Step
5: Next, you want to solve the
problem.
$5.58
- $3.50 = $2.08 (This
tells you how much
was paid for writing
each individual check
at 8 cents a per check.)
$2.08
divided
by
.08
= 26 (Remember,
that
8 cents
is
written
as
.08
as
you
are
working
with
money
in
this
problem.)
Your final answer is 26 checks written by Mike in the
month of October.
-
Step
6: Now that
you have an answer, check that answer.
.08 x 26 checks =
$2.08 which is the
fee for the writing the
checks.
$2.08
+ $3.50
= $5.58
It works and "checks" out.
Then check to see if 26 is one of your 4 choices for the question.
After looking over the
4 choices, you notice that choice B has the
same answer, 26 checks. Excellent!
CHOICE B is
the one you want to select.
