In the formula, let p = 2500, r = 0.03 and t = 4. See picture.
We want to find an inequality that says how many outfits Samantha could buy.
The solution is x ≤ 2
We know that she has $600 to spend.
She already spent:
- $392.25 in her bicycle
- 3 bicycle reflectors for $7.01 each, so the total is: 3*$7.01 = $21.03
- $34.96 in a pair of gloves.
The total amount she already spent is:
$392.25 + $21.03 + $34.96 = $448.24
The <u>amount of money that she has left</u> is:
$600 - $448.24 = $151.76
Ok, now we know that each outfit costs $75.88
So the price of x of these will be x times $75.88
price = $75.88*x
This must be equal or smaller than the amount of money that she has left:
$75.88*x ≤ $151.76
x ≤ $151.76/$75.88 = 2
x ≤ 2
This is the inequality that represents the number of outfits that she can buy.

Answer:
Greta will be earning 3.6/h more at her new job.
Step-by-step explanation:
To find the difference subract Greta‘s salary from her current job from Greta’s salary from her future job.
To find Greta’s salary (numerator) at her future job divide her current weekly salary ($729) by 45h then multiply that answer (16.2) by the increase in salary 10% or 1.1. You should end up with $17.82- this is your numerator. To find the denominator divide her current hours (45h) by 45 then multiply that answer (1) by 0.9 which is the 10% decrease in hours. Now you have a fraction ($17.82/0.9) then multiply that fraction by 1.1/1.1 to get the denominator to 1 hour so you can subtract the fractions. You should end up with $19.8/h.
Now subtract Greta’s current salary ($16.2/h)- you just take the numbers from the first part before you increase or decrease- from her future salary ($19.8/h), you will end up with 3.6/h.
I was challenged to write this in a single equation:
[((($729\45h)x1.1)/((45h\45)x0.9))x1.1/1.1]-[($729\45h)/(45h\45)]
=$3.6/h
/ means a fraction bar
\ means division
