Example 7: What is the combined thickness of these five shims: 0.008,

0.125, 0.15, 0.185, and 0.005 cm?
Analysis: The phrase combined thickness tells us that we need to add
these five decimals to get their sum.
Answer: The combined thickness of these five shims is 0.473 cm.
Example 8: Melissa purchased $39.46 in groceries at a store. The cashier

gave her $1.46 in change from a $50 bill. Melissa gave the
cashier an angry look. What did the cashier do wrong?
Analysis: We need to estimate the difference to see if the cashier made
a mistake.
$50.00 - $40.00 = $10.00
Estimate: $1.46 is much smaller than the estimated difference of $10.00.
So the cashier must have given Melissa the wrong change.
Example 9: In Example 8, how much change should Melissa get from the
cashier? The cashier gave her $1.46
Analysis: We need to find the difference of $50 and $39.46.
Answer: $50.00 - $39.46 = $10.54
Example 10: If a 10-foot piece of electrical tape has 0.037 feet cut from it,
then what is the new length of the tape?.46
Analysis: We need to subtract: 10 - 0.037 and express the answer with
proper units.
Answer: 10 ft. - 0.037 ft. = 9.963 ft.
Summary: In this lesson we learned how to solve word problems involving decimals. We
