A construction company used the algebraic expression 24x + (25) (4.5) to calculate the total cost of a customer's new driveway. Which is the coefficient in this expression?

Right answer:24

In an algebraic expression, the coefficient is the number that multiplies the variable. Note that if this coefficient is one (1) it is omitted.

In the case of this algebraic expression with two terms:

24x + (25) (4.5) = 24x+112.5

-The first term is 24x

-and the second term is 112.5.

The variable is x (which is the value that has to be found) and 24 is the number that multiplies the variable, hence it is the coefficient.
