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
Also I am just a student so please tell me if you find any mistakes I could fix or any suggestions to make this a better explanation, and if you have any questions ask away.
Answer:
200 is the number of sandals
500 is the number of shoes
Step-by-step explanation:
x is the number of sandals
y is the number of shoes
so 2.5x + 4y = 2500
=> x = (2500 - 4y)/2.5
In the month of April, the numbers of shoes doubles
2.5(2x) + 4y = 3000
5x + 4y = 3000
Substitute x = (2500 - 4y)/2.5
5(2500 - 4y)/2.5 + 4y = 3000
5000 - 8y + 4y = 3000
-4y = - 2000
y = 500
x = (2500 - 4y)/2.5 = (2500 - 4(500))/2.5
x = (2500 - 2000)/2.5
x = 500/2.5 = 200
