Step-by-step explanation:
We need to calculate the total time. We are given two functions that when summed up will give you total time.

Answer:
$287.82
Step-by-step explanation:
60 * 2.30 = 138
30 * 2.75 = 82.5
34 * 1.98 = 67.32
138 + 82.5 + 67.32 = 287.82

Step-by-step explanation:
The element at row i column j in the product is the dot-product of row i of the first matrix and column j of the second matrix. For example, row 2 column 1 of the product is ...
(row 2) · (column 1)
[3, -2, 4] · [2, 7, 1] = (3)(2) +(-2)(7) +(4)(1) = 6 -14 +4 = -4
The attachment shows the complete product matrix. It is convenient to let a spreadsheet or graphing calculator do the tedious repetitive arithmetic.
