The answer would be A. If it wasn't limited to a one digit number multiplied by a power of 10 then the answer would be 9.06*10^10, but the limitation requires a single digit leaving only the answer 9*10^10 because 10^10= 100,000,000,000. That multiplied by 9 would give you 900,000,000,000.

Answer: desktop = $1750, laptop = $1900

<u>Step-by-step explanation:</u>

Let x represent the cost of the desktop

.07x + .055(x + 150) = 227

.07x + .055x + 8.25 = 227

.125x = 218.75

x = 1750

desktop (x) = $1750

laptop (x + 150) = $1750 + $150 = $1900
