Answer:

$140

Step-by-step explanation:

When a variable is placed directly after the coefficient (the number) with no symbols between them, we are supposed to multiply the two together. The variable <em>x</em><em> </em>represents the number of hours this person will spend cleaning your house, and we are trying to find the cost of 4 hours of cleaning. Therefore, we will substitute 4 for <em>x</em>:

f(x) = 35x \\ f(x) = 35(4)

Then, we multiply 35 by 4:

f(x) = 35(4) \\ f(x) = 140
