Rosalie earns extra money by working as a babysitter over the weekend. She charges $10 to drive to the home and an additional $8 per hour. what are the input and output values?

Answer :

input values are the number of hours she babysits
output values are the cost of babysitting

Answer:

Input value is the number of hours Rosalie works

Output value is total earning of Rosalie

Step-by-step explanation:

In mathematics, in any function, input are the values which are fed to obtain some result. this result is stated as output value. Both values are variable.

Now, in the given question, consider the earning of Rosalie as out put expressed as y. The number of hours Rosalie work is input value and is expressed as x.

Please note that the charges for travelling which is $10 and cost of per hour baby sitting which is $8 are constant values and doesn't belong to input or output.

We can built a relation here,

y = 8x + 10

For example if Rosalie worked at weekend for 5 hours, here earning which is 'y' can be calculated by above equation.

y = (8)*(5) + 10

y = 40 + 10

y = 50

So, if Rosalie work for 5 hours on weekend, she would earn $50.
