Question

A circuit overloads at 2000 watts of electricity. A microwave that uses 1150 watts is plugged into the circuit. Write and solve an inequality that represents the additional number of watts you can plug in without overloading the circuit?

Answer 1

Let x represent the additional power allowed before exceeding the maximum rating of the circuit. then 1,150 + x must be less than 2,000 to prevent overload:

1150 + x < 2000.

This means that x must be less than 2000 - 1150 = 850 Watts.

1150 + x < 2000
1150 + x - 1150 < 2000 - 1150
x < 2000 - 1150
x < 850.

Don't plug in anything that uses more than 850 Watts into this circuit to prevent overloading it.

thank you!
