Answer:
Stephanie has more than $900
Step-by-step explanation:
Represent the unknowns: a for Alexandra and s for Stephanie.
Then a + s > $2,500, and a = s + $700.
Substituting the latter into the former equation, we get:
(s + $700) + s > $2,500, or
2s > $1800
Then s > $900; Stephanie has more than $900.
The correct option is 4. PSU.
The hardware part that would be checked next is PSU.
<h3>What is Power Supply Unit PSU?</h3>
An internal piece of IT hardware is known as a power supply unit (PSU). Despite their name, power conversion devices, or PSUs, do not really supply power to systems.
Some key features of PSU are-
- A power supply specifically transforms alternating high voltage current (AC) to direct current (DC) and regulates the DC output voltage to the precise tolerances needed for contemporary computing components.
- There is, however, a PSU substitute that may be utilized in specific circumstances.
- Electrical power can be transported inside network cables using Power over Ethernet (PoE), freeing the device from being bound to an outlet.
- Because PoE can deliver wireless access points wherever it is most convenient and uses less room for wiring, it is perfect for systems that need greater flexibility.
