You have $7 and earn $0.25 for each cup of orange juice you sell. Write an equation in two variables that represents the total amount A (in dollars) you have after selling j cups of orange juice.

The equation is A = 0.25j + 7

Step-by-step explanation:

In this question, we are asked to write an equation that shows the total amount of money someone has after selling a particular amount of orange juice.

To solve this question, we can just consider the total number of orange glasses cups sold. Firstly , let’s write the revenue generated from the sales.

She sells j cups A $0.25 per cup. The total amount of money made here is equal to 0.25j.

When we add this to the initial $7, we have the final equation.

0.25j + 7

The amount A in dollars is equal to this.

A = 0.25j + 7

whatever you can spend with $11.53 or under.

step-by-step explanation:

20 - 8.47 = 11.53. take away the money he used for lunch from the starting amount of 20.

option 2 is correct.

step-by-step explanation:

we are given two inequality equation

x+y> 5 and -3x+2y< -2

first we draw the graph of both function using t-table method

equation: x+y> 5

for x=0, y=5

for x=-5, y=0

table:

x   :   0     5

y   :   5     0

test point (0,0) , 0> 5

false

equation: -3x+2y< -2

for x=0, y=-1

for x=2, y=4

table:

x   :   0     2

y   : -1       4

test point (0,0) , 0< -2

true

now we draw the graph. see the attachment for graph.

common region would be solution set.

option 2 is correct.
