This is a basic subtraction problem :-).
You will subtract how much money the mechanic gives to the supplier; which in this case will be $20, by the total amount of the parts which is $14.56.
20-14.56 = 5.44
Therefore, he will receive $5.44 in change for the transaction.
The percent error is 25 %
<em><u>Solution:</u></em>
Given that it is estimated that there are 50 students in the seventh grade class, but there are actually 40
<em><u>To find: percent error</u></em>
Percent error is the difference between a measured and known value, divided by the known value, multiplied by 100%
<em><u>The formula for percent error is given as:</u></em>

Here, exact value = 40 and approximate value or estimated value = 50
Substituting the values in above formula,

Thus the percent error is 25 %
The mode is the number that shows up the most.
In the dataset, note that the stem should be in the tens place, and the different number of leaves are in the ones place.
62 shows up one more time than all the other numbers, and so 62 is your answer.
