Answer:
15
Step-by-step explanation:
If the company has 5 different exterior designs, and there are three interior plans that can be incorporated in any of the five exteriors, we can mix any of these 5 exteriors with any of the 3 interior plans.
Therefore we would have 5 x 3 ways of choosing.
Thus, there are 15 different ways that the exterior and interior plans can be offered to potential home buyers.
Answer:
(20 + n)¢
Step-by-step explanation:
With Company X, it costs 35¢ to connect and then 5¢ for each minute.
So, for n minutes of calling the company X charges, C(x) = (35 + 5n)¢
Again, With Company Y, it costs 15¢ to connect and then 4¢ for each minute.
So, for n minutes of calling the company Y charges, C(y) = (15 + 4n)¢.
Therefore, the company Y charges for n minutes of calling less than company X is [(35 + 5n) - (15 + 4n)]¢ = (20 + n)¢ (Answer)
The equation is 3.75 x c = p
Amount = A = $50(1 + 0.03/12)^(12*m), where m is the # of months. Note that A= $50 at the beginning (when m=0). Note that I am assuming that "3%" is ANNUAL interest.
If, on the other hand, "3%" is monthly (very unlikely!!), then:
Amount = A = $50(1 + 0.03)^(m)
