Answer:
87.5
Step-by-step explanation:
87.5 because if your earning a 3.5% of the $500 then that means you're earning 17.5 dollars.in an year therefore in five years you multiply the 17.5 x 5 years which will give you at 87.5 so we've had in total you can get to 587.5 dollars
Cost Price for oil change =$27
Charge for the customers =$40
Markup cost = Difference between selling price and cost price =$40-$27=$13
To find the percent of markup, divide the markup cost by the cost price and multiply it by 100.
Markup percent = (13/27)*100
=48.15%
Hoarder of erasers :o
Is this suppose to be a riddle or sum
Answer:
-880.75
Step-by-step explanation:
Subtract 912 from 20.25 first then add 11.
1. Solve for x in 4x-2y+7=33
4x-2y+7=33
4x+6=33+2y
4x=33+2y-7
4x=2y+26
x=(2y+26)/4
x=(2(y+13))/4
x=(y+13)/2
2. Substitute x=(y+13)/2 into 5y=3x-30
5y=3x-30
5y=3*(y+13)/2 -30
5y=(3(y+13))/2 - 30
3. Solve for y in 5y=(3(y+13)/2 -30
5y=(3(y+13))/2 - 30
10y=3(y+13)-60
10y=3y+39-60
10y=3y-21
10y-3y=-21
7y=-21
y=-21/7
y=-3
4. Substitute y=-3 into x=(y+13)/2
x=(y+13)/2
x=(-3+13)/2
x=5
5. Therefore,
x=5 and y=-3
I hope you have a nice day :D
