h = hours

1.75h + 4 <_ 18

or 1.75h + 4 is less than or equal to 18

(a)0.75x+1200=3.50x

(b)$x=436.36\approx 436, Break-Even \:Point$

(c)0.75x+1200<3.50x

(d)$x436.36\approx 436$

It means the store needs to sell more than 436 funnel cakes to make a profit

Step-by-step explanation:

Given the Cost and revenue function of John boy and Mary Ellen's food stand below:

C= 0.75x+1200.

R=3.50x

(a)When Cost = Revenue

Then:

0.75x+1200=3.50x

(b)To solve the equality from part (a) above

0.75x+1200=3.50x

Collect like terms

1200=3.50x-0.75x

1200=2.75x

Divide both sides by 2.75

$x=436.36\approx 436$

When Cost equals revenue, it is the Break-Even Point. It means the food stand will have to sell 436 funnel cakes to break even.

(c) When Cost is Less than Revenue

$C(x)<R(x)\\0.75x + 1200<3.50x$

(d)Solving the inequality

C(x)<R(x)

0.75x + 1200<3.50x

Collect like terms

1200<3.50x-0.75x

1200<2.75x

Divide both sides by 2.75

$436.36<x$

$x436.36\approx 436$

It means the store needs to sell more than 436 funnel cakes to make a profit.

6 > 6 - a

3 < 3 + c

Step-by-step explanation:

Since you are told that there are less than six assignments, a represents what is taken away from the six. the result of 6 - a would be less than 6 itself.

Same concept can be connected with the other example. this time c is what you add to the 3 chores. The value of 3 + c will be greater than 3 itself

Hope this helps.

5x - 8 < 37 and x < 9

Step-by-step explanation:

again, sorry if it's wrong.

5x - 8 < 37

+8   +8

5x < 45

5     5

x < 9
