The topic is critical path 12th grade and the subject is math of industry and government. Pls help and list the paths too ‼️‼️

  see below

Step-by-step explanation:

The difference between start and end times is the duration in each case.

The earliest start time is the latest of the earliest finish times of all predecessor tasks. These are computed working left to right.

The latest finish time is the earliest of the latest start times of all successor tasks. These are computed working right to left.

Where earliest and latest times are the same, the task is on the critical path. (It has no slack time.)

The above computations have been built into the attached spreadsheet. Here, predecessors and successors are handled manually. In appropriate scheduling software, they would be handled automatically by the specification of the task relationships.

$53.50

step-by-step explanation:

you have to subtract the amount of money chuck earned ($72.50) by the cost of the gas for the mower ($11.25) and the new string for the trimmer he bought ($7.75).

72.50-11.25=61.25

and then subtract $61.25 by the second thing he bought (the new string for the trimmer)

61.25-7.75=53.5

so in total it's $53.50 (53 dollars and 50 cents)
