Answer
• A. Equation: 25(5 + x) = 325
,
• B. Answer: 8 dogs
Explanation
Given
• Charge to wash a dog: $25.
• She washed 5 dogs on Saturday and then some more on Sunday.
• She made $325 for the weekend.
Procedure
She charges $25 per wash, she made $325 for the weekend, and we know that on Saturday she washed 5 dogs, but we don't know how many she washed on Sunday. Thus, we have to build an equation in which the number of dogs washed on Sunday is represented by x (as we do not know the real number).
Considering that the total money made has to be equal to the multiplication of the charge times the dogs washed, the equation is:
Then, we have to solve for x to know how many dogs did she wash on Sunday.
0. Multiplying the parenthesis
<em>2. Subtracting 125 from both sides of the equation</em>
<em>3. Dividing both sides of the equation against 25</em>
Value of a and b that completes the mapping diagram will be a=0 and b=1
• Mapping diagram simply means a function that has a special type of relation where the elements of the domain are paired with that of the range.
• Mapping diagram consists of two parallel columns, the first column depicts the domain of the function whereas the second column depicts the range.
• Lines are drawn from first column to second column i.e. from domain to range, to represent the relation between 2 elements.
• Mapping is quite similar to making a flowchart, showing input and output values.
• Point to be noted that every mapping is a relation but every relation is not a mapping.
