Please help with these two questions I put it to be 24 points please help me I would really appreciate it

For the first one just read it put it has to be 90 words

And the second one you have to make up a word problem with 50 words and the second part you have to show how you can rewrite the problem using at most 25 words please help me

1. $6.20

2. Samantha has $79, she decides to go to the mall and buys 6 dresses that are $7 each. She thinks that she might not have enough money so she returns 2 dresses. She then finds out that she has more than enough so she buys a candy bar for $5. How much money does she have left?

Step-by-step explanation:

1. you can write an equation to represent the word problem

20-(2.10+0.9x)

20-(2.10+0.9(13)

20-(2.10+11.7)

20-(13.8)

6.2

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is

both graphs increase on their domain

neither graph has a y-intercept

step-by-step explanation:

the following points can be visualized easily from the graph
