Question

A plumber uses the expression 48 + 25h to determine the number of dollars to change each customer. If H = 4 how much does the customer pay ?

Answer 1

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 2

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 :

$E=48+25h~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)$

We are to find the amount that customer paid if h = 4.

Substituting the value of h in equation (i), we get

$E=48+25h=48+25\times4=48+100=148.$

Thus, the customer paid $148.
