Cost = fix cost + hourly cost - discount
Cost = 4* [5 + 4x - 4x(20/100)] = 4*[5 + 4x - 0.8x] = 4*[5 + 3.2x] = 20 + 12.8x
Answer: option B) 12.8x + 20
Answer:
The answer to your question is the third choice
Step-by-step explanation:
To solve this problem, just multiply 6 by each of the numbers of the matrix and simplify.
6 | 4 -2 1 | = | (6 x 4) (6 x -2) (6 x 1) |
| 7 3 0| | (6 x 7) (6 x 3) (6 x 0) |
= | 24 -12 6 |
| 42 18 0 |
The first choice is wrong because only multiply by six the first row.
The second and fourth rows are incomplete.
