Jeff sells popcorn for $3 per bag. To make a profit each day, he needs to sell at least $120 worth of popcorn. He has sold $36 w
Zepler [3.9K]

Answer:

The inequality tha can be used to find how many more bags of popcorn Jeff still needs to sell today to make a profit is

x - 12 ≥ 40.

Step-by-step explanation:

Let us represent the number of bags of popcorn as p

Jeff sells popcorn for $3 per bag. To make a profit each day, he needs to sell at least $120 worth of popcorn.

We have the equation:

$3 × p ≥ $120

3p ≥ $120

p ≥ 120/3

p ≥ 40 bags

He must sell at least 40 bags to make a profit

He has sold $36 worth of popcorn today.

1 bag is $3

Hence, he has sold

$36/$3 = 12 bags of popcorn

Which inequality can be used to find Jeff still needs to sell today to make a profit?

This equality is given as:

x - 12 bags ≥ 40 bags

x - 12 ≥ 40

x ≥40 - 12

x ≥ 28 bags

She still need to sell 28 more bags of popcorn.

Name the property shown by each statement.
vlada-n [284]
Most of these problems are the commutative property:

Addition
a + b = b + a

Multiplication
a * b = b * a

and the associative property:

Addition
(a + b) + c = a + (b + c)

Multiplication
(a * b) * c = a * (b * c)

There's also the Identity property:

Addition \ Subtraction:
a + 0 = a \ a - 0 = a

Multiplication \ Division:
a * 1 = a \ a / 1 = a

Please help me will mark brainliest!!!<br><br> Provide a hand drawn graph attachment pls
Travka [436]

The graph is shown below. I used GeoGebra to create the graph. The graph is restricted on the domain 0 \le x \le 2 meaning that everything to the left of x = 0 is not drawn, and the same for everything to the right of x = 2.

A table of values is included as well. Each row in the table represents an ordered pair point (x,y) that is on the blue cosine graph.
