dig deeper if items plugged into a circuit use more than 2400 watts of electricity, the circuit overloads. a portable heater that uses 1050 watts of electricity is plugged into the circuit.
a. find the additional numbers of watts you can plug in without overloading the circuit.
b. in addition to the portable heater, which two of the following items in the table can you plug in at the same time without overloading the circuit?

Explanation:

Step1: Find the additional number of watts

The total capacity is 2400 watts. The portable heater uses 1050 watts.
$$2400 - 1050=1350$$

Step2: Check combinations for part b

• Aquarium (200) + Television (150) = 350
• Aquarium (200) + Vacuum cleaner (1100) = 1300
• Aquarium (200) + Hair dryer (1200) = 1400 (over 1350, not valid)
• Television (150) + Vacuum cleaner (1100) = 1250
• Television (150) + Hair dryer (1200) = 1350
• Vacuum cleaner (1100) + Hair dryer (1200) = 2300 (over 1350, not valid)

Answer:

a. 1350
b. Television and Hair dryer; Aquarium and Vacuum cleaner; Television and Vacuum cleaner
