Mathswatch Question! Mr Powers checks his electricity bill. Here are his meter readings. New reading: 6538 units, Old reading: 6245 units. Calculate the cost of the number of units used?

Sagot :

Answer:

[tex]Cost = 284 x[/tex]

Step-by-step explanation:

Given

[tex]Old = 6245\ units[/tex]

[tex]New = 6538\ units[/tex]

Required

The cost of units used

First, calculate the number of units used.

[tex]Units = New - Old[/tex]

[tex]Units = 6538 - 6254[/tex]

[tex]Units = 284[/tex]

Next, multiply the units used by the cost per units,

Since the cost per unit is not given, we assume that it is x.

So, the total cost is:

[tex]Cost = Units * Cost\ per\ units[/tex]

[tex]Cost = 284 * x[/tex]

[tex]Cost = 284 x[/tex]
