como calcular la cantidad de horas por proyecto si un contratista tiene 5,000 horas-hombres y el costo es de $10 y $12 por proye
Tju [1.3M]

Answer:

Each project has 2.500 man-hours

Step-by-step explanation:

Available man hours: 5000

For two projects          Costs $

X: project A                     10

Y: project B                     12

Approach:

X + Y = 5000 => X = 5000 - Y

10 * X + 12 * Y = 55000

replacing:

10 * (5000 - Y) + 12 * Y = 55000

50000 - 10 * Y + 12 * Y = 55000

2 * Y = 55000 - 50000

Y = 5000/2

Y = 2500

For X:

X = 5000 - 2500

X = 2500

The number of hours available for each project are:

Projects Man            hours

X: project A              2500

Y: project B              2500

The Smith Family went out to to dinner.
KatRina [158]
First I will find the tip and then I will add that to the total and THEN I will add my sales tax to find 6% you have to multiply by 0.06.  to find 15% you have to multiply by 0.15

0.06 * 29.85 = 1.79
29.85 + 1.79 = 31.64
0.15 * 31.64 = 4.74
31.64 + 4.74 = $36.38
