Respuesta :
Given, the cost of a chordless phone = $55
Cost for each handset = $25
Now to find cost for 3 handsets, we have to multiply cost for each handset with number of handsets.
So, the cost for 3 handsets = $(25×3) = $75
We have to find the total cost of a chordless phone and 3 extra handsets.
To find the total cost we have to add the cost of a chordless phone and cost of 3 handsets.
Therefore, the total cost = $55 + $75 = $(55+75) = $130
We have got the required answer.
The total cost is $130.
