Grace's favorite activities are going to the movies and skating with friends. She budgets herself no more than $75 a month for entertainment and transportation. Movie admission is $9 per movie, and skating costs $5 each time. A student bus pass for the month costs $25.

Consider the restrictions on the numbers in the scenario
Real or integers or whole

[lapis sleet]

i js dont get how ik if its a real number interger or whole

XeR

YeR

[cedar widget]

well we can have decimal values for dollars

so integers and whole are not correct

it should be XER, X>= 0

[lapis sleet]

how do ik its a real number in a word problem like thus by js looking or a integer or whole

[cedar widget]

whole numbers are all integers 0 and up

wait I misunderstood the question

[lapis sleet]

yeah so basically i need inequalities to make

i have x+y >= 12

x+y >= 5

X>=2

i get all that stuff but when it tell me to consider the restriction on the nimbers in the scenario

shit doesnt make sense

[cedar widget]

essentially u have to consider the word problem and what values are possible

[cedar widget]

what are the "numbers" in this last sentence

just the $ amounts?

[lapis sleet]

yeah

[cedar widget]

ok so dollars can be decimals right

like $4.50

so they are not only whole numbers

and not only integers

so they are real numbers

however they can't be negative in this scenario

so the numbers in this scenario exist in real numbers but are greater than 0

Whole numbers are non decimal non fractional numbers over and including 0, integers are non decimal non fractional numbers above, below and including 0, and real numbers are all numbers. So when we are considering dollar amounts they are real numbers over 0 (unless we are talking about debt)

[lapis sleet]

okay thank u

.solved

[winged granite]

Solved

Post marked as solved by @lapis sleet.

Use .unsolved if this was a mistake.

[lapis sleet]

@cedar widget

they asking me the cordinates of these ion get it

[cedar widget]

send the whole question I don't get what they asking

[lapis sleet]

my byddy did that i dony get ut

all this makes no sense either the 0,0 is not a solution or is idk@how to find that out

[cedar widget]

question 2?

just look at the shaded region and pick 3 points

[lapis sleet]

yep

oh

okay

wiat what

wtf

im so confused idk y

[cedar widget]

which question u confused with

[lapis sleet]

same number 2

[cedar widget]

send that one and pls not sideways lol

do u know what coordinates are?

[lapis sleet]

yeah thr part where the dots like

connect

idk how to explain it

like

-2,4 perhaps there should be s dot there

[cedar widget]

coordinates are written as (x, y)

[lapis sleet]

how did i get those numbers tho

[cedar widget]

do u know the x and y axis?

[lapis sleet]

is it js any number in the shaded part

yeah

x is across y is up down

[cedar widget]

so yeah u choose an x and y that meet in the shaded part

[lapis sleet]

okay nd wb this

[cedar widget]

for example lets take (-2,4) which ur friend picked

[lapis sleet]

nvm go on

[cedar widget]

u look at where -2 on the horizontal axis is

and draw a line vertcially there

and u find where 4 on the y axis is

and drag a line horizontally there

the point (-2, 4) corrisponds with where those 2 points meet

and it is in the shaded part

[cedar widget]

now for this

[lapis sleet]

i js dont get the part where it asks me if 0,0 is a solution

[cedar widget]

basically

(0,0) is when x=0 and y=0

so sub in those and see if the inequality is true

lets take 1.a)

y-x>=10

sub in (0,0)

u get 0-0 >= 10

which isn't correct

so (0,0) is not a solution

[lapis sleet]

oh

shit
