Question

help please

Answer 1

let

x = # of type A
y = # of type B

type A brings in a profit of $45 each, so selling x of them will gain you 45x dollars
type B brings in a profit of $35 each, so selling y of them will gain you 35y dollars

In total, you'll get a profit of 45x+35y dollars

This must be at least $3850, so

45x+35y >= 3850

Answer 2

you sell a total of x+y printers, so because "You expect to sell at least 100 laser printers this month", this means

x+y >= 100

Answer 3

if you graph those two inequalities, along with

x >= 0
y >= 0

you'll get a feasible region and the vertices of that feasible region will be where the min cost occurs

Answer 4

it turns out that there are 3 vertices and they are

(0, 110), (35, 65), (100, 0)

these are the points where the boundary lines intersect

Answer 5

now what you do is plug each vertex into the cost function C = 86x + 130y and see which vertex produces the smallest value of C

Answer 6

How's that possible?

Answer 7

The large tiles used can't even fit the largest area of mosaic

Answer 8

@.Sam.

Answer 9

theses are answer we will obtain
0 small tile
6 large tiles
minimum cost $27

Answer 10

If the mosaic area is 60x40 then that could be possible

Answer 11

Because for large tiles is 12x6, so when we have 5 of them then it's 60x30, which is inside the 60x40

Answer 12

we have to solve iit through linear function

Answer 13

@.Sam.

Answer 14

Area of mosaic=2400
\[12x+6y \leq 2400\]

Answer 15

how did we get 2400

Answer 16

and mostt precisely how did we got 60 and 40
