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

Faith and Trinity are making cookies for Valentines day. Together they make a total of 88 cookies. Trinity makes 40 cookies more
malfutka [58]

Answer:

Faith made = x = 24 cookies

Trinity made = y = 64 cookies

Step-by-step explanation:

Faith and Trinity are making cookies for Valentines day. Together they make a total of 88 cookies. How many cookies did each girl make?

Let the number of cookies

Faith made = x

Trinity made = y

x + y = 88

Trinity makes 40 cookies more than Faith.

y = x + 40

We substitute

x + y = 88

x + x + 40 = 88

2x + 40 = 88

2x = 88 - 40

2x = 48

x = 48/2

x = 24 cookies

y = x + 40

y = 24 + 40

y = 64 cookies

Therefore:

Faith made = x = 24 cookies

Trinity made = y = 64 cookies
