Answer:
- ribeye steak: $24.37
- grilled salmon: $9.30
Step-by-step explanation:
If we let r and g represent the costs of a ribeye steak dinner and grilled salmon dinner, respectively, the sales figures give rise to two equations.
17r +15g = 553.74
22r +5g = 582.65
If we multiply the second equation by 3 and subtract the first, we have ...
3(22r +5g) -(17r +15g) = 3(582.65) -(553.74)
49r = 1194.21
r = 1194.21/49 ≈ 24.37
g = (553.74 -17r)/15 ≈ 9.30
The steak dinner costs $24.37; the salmon dinner costs $9.30.
_____
<em>Check</em>
17(24.37) +15(9.30) = 553.79 . . . not 553.74
22(24.37) +5(9.30) = 582.64 . . . not 582.65
There is no exact solution to this problem.
Hi!
The correct answer is B. The value of M is a product of N and a factor that does not depend on N.
That is true because the relation is : M(t) = N * (1+r)^t , N is N and (1+r)^t is a factor that does not depend on N.
Also, because none of the other answers is true, it makes easier for B to be the one true answer, explanation:
A. The initial value is (1+r) - WRONG, the initial value is N, it says that
C. The function is linear - WRONG, we have exponential growth here, because of the factor (1+r)^t
D. N increases each month - WRONG, N is the initial number of members and it does not change.
Hope this helps!
