Michael charges $5 an hour to babysit which of the following expresses the amount of money Michael gets paid as a function of how many hours he babysit

f (x) = 5x

f (x) = x+5

f (x) = x

f (x) = x/5

The proper function for nanny pay based on the number of hours worked is:

f (x) = 5x

Step-by-step explanation:

Since it is recognized that the hourly payment is $5, a function must be used with the use of a letter whose definition is: number of hours worked, which in this case is X.

The correct operation to use to mention that a fixed price increases as the number of units increases is multiplication, so the function is used:

f (x) = 5x

We will proceed to check it as follows: suppose the babysitter worked for 4 hours, logic would tell us that the total payment would be $20, but we will replace this value in the function:

f (x) = 5 (4) f (x) = 20

With which it is checked.

5x

Step-by-step explanation:

Micheal starts with no money so the only number should be right next to the variable (x) being multiplied.

every hour (x) he gets payed $5 so 5x
