y=$130x-$18

Notice that each day rent is 18, so the money he owes grows up 18 per day : 18x

Joanna pays a flat rate of $74 for her cell phone and is charged $0.08 for every text she sends. Her goal is to spend no more than $96 on her phone bill each month. Which inequality will help her determine the minimum number of texts she sends per month?

$74 + $0.08x ? $96

$74 + $0.08x ? $96

$74 + $0.08x < $96

$74 + $0.08x > $96 

I picked $74 + $0.08x > $96

lets say your height is no more than 6 feet

ganeshie8 · Answer

you represent that using : 
$$\large \text{height } \le 6$$

right ?

anonymous · Answer

yes

ganeshie8 · Answer

`no more than 6 feet` means your height could be 6 or less
but it can never be more than 6 feet

anonymous · Answer

okayy

anonymous · Answer

i dont understand why 6 feet is relevant...

ganeshie8 · Answer

`Her goal is to spend no more than $96`

anonymous · Answer

yes

ganeshie8 · Answer

so you need to use  $\large  \le 96$ inequality here too

anonymous · Answer

got it!

ganeshie8 · Answer

you can replace `no more than`  with  $\large \le$

anonymous · Answer

so it is $74 + 0.08x greater than or equal to 96

ganeshie8 · Answer

it should be  :

$74 + 0.08x `less` than or equal to 96

ganeshie8 · Answer

the left side quantity should be less than or equal to 96

ganeshie8 · Answer

because her pocket money is only $96

ganeshie8 · Answer

she cannot pay more than 96

anonymous · Answer

ooooh okay got it
