If H = 4, we simply plug 4 into the position of h in the expression.
48 + 25 * 4
48 + 100
148
The customer pays $148
Answer: The customer paid $148.
Step-by-step explanation: Given that a plumber uses the following expression to determine the number of dollars to charge each customer :
[tex]E=48+25h~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)[/tex]
We are to find the amount that customer paid if h = 4.
Substituting the value of h in equation (i), we get
[tex]E=48+25h=48+25\times4=48+100=148.[/tex]
Thus, the customer paid $148.
