Marcus and Tony work for Lombardo's Pipe and Concrete. Mr. Lombardo is preparing an estimate for a customer.
He knows that Marcus lays a slab of concrete in 9 hours. Tony lays the same size slab in 6 hours.
If both work on the job and the cost of labor is $ 49.00per hour, decide what the labor estimate should be.
~~~~~~~~~~~~~~~~~~~~~~~~~~
The problem is posed / (is worded) incorrectly.
In order for it be correct, the problem must say / (must DEFINE) what
the entire job is, which is the subject of estimating.
How the cost of labor is described in the post, is absolutely shocking, incorrect and absolutely illiterate.
To be correct, this piece of the post must say "the cost of labor is $49.00 per hour per person" -
- then it would be a complete/exhaustive description, otherwise it is an open interpretation
if $49 is the combined rate for both workers per hour or for each worker per hour individually and separately.
Would I be a supervisor of these "writers", I would fired them immediately.
Consider to hire 1 - 2 - 3 - 7 - 9 specialists to edit your writing after you . . .
