r - annual inflation rate in decimal form
t = number of years from now
Given that,
C = $ 123, 000
t = 23 years
Substituting the values in formula,

Answer:
15x + 180 ≥ 900
x ≥ 48
Step-by-step explanation:
x = amount of laptops needed to sell.
Equation:
15x + 180 ≥ 900
15x ≥ 720
x ≥ 48
Check:
15(48) + 180 = 900
720 + 180 = 900
900 = 900 (It's good, she needs to make at least 900, so she needs to sell at least 48 laptops).
