Answer:

Hence, (75,40) is the maximum point and maximum profit is $192.5

Step-by-step explanation:

Let the breakfast be x

And let the lunch or afternoon be y

Inequalities will become

$\frac{1}{3}x+\frac{1}{2}y\leq 45$

$\frac{2}{3}x+\frac{1}{2}y\leq 70$

And objective function will be

Z=1.5x+2.0y

You can see the graph in the attachement

ABCD is the feasible region

Points of feasible region is (0,90) ,(0,0) ,(75,40) and(105,0)

We have to find Z by substituting the points of feasible region

At (0,90) we get

Z=1.5(0)+2(90)

Z=180

At (0,0)

Z=1.5(0)+2(0)

Z=0

At (75,40)

Z=1.5(75)+2(40)

Z=192.5

At (105,0)

Z=1.5(105)+2(0)

Z=157.5

The maximum number we are getting is 192.5 which is at (75,40)

Hence, (75,40) is the point of maximum

A. -9

*The answer must have a negative sign.*

Step-by-step explanation:

Lesson: Dividing integers

First, you divide by the numbers from left to right.

$72/8=9$

It change positive to negative sign.

$72/9=8$

Then, you can also multiply by the numbers from left to right.

$9*8=72$

Final answer is -9

Hope this helps!

Have a nice day! :)

Evaluate f + g2 - 3g if f= 3 and g = 5.

dolphi86 [110]

Answer:

$\boxed{ \bold{ \huge{ \boxed{ \sf{13}}}}}$

Step-by-step explanation:

Given, f = 3 and g = 5

$\sf{f + {g}^{2} - 3g}$

Plug the values

⇒ $\sf{3 + {5}^{2} - 3 \times 5}$

Evaluate the power

⇒ $\sf{3 + 25 - 3 \times 5}$

Multiply the numbers : 3 and 5

⇒ $\sf{3 + 25 - 15}$

Add the numbers : 3 and 25

⇒ $\sf{28 - 15}$

Subtract 15 from 28

⇒ $\sf{13}$

Hope I helped!

Best regards! :D
