You can plug 1350 or less watts without overloading the circuit.
Step-by-step explanation:
Given,
Circuit overloads at = 2400 watts
Electricity consumed by portable heater = 1050 watts
Let,
x be the additional number of watts you can plug in.
Portable heater + additional watts ≤ Overloading limit
1050 + x ≤ 2400
Subtracting 1050 from both sides
You can plug 1350 or less watts without overloading the circuit.
