Given parameters:
Mark up percentage = 150%
Original cost = $488
Sales tax = 5%
Unknown:
His total cost = ?
Solution:
Marking up a good is the amount a sell adds to a product which makes its selling price usually for a profit.
Since the emerald was marked up by 150%;
New cost = (1 + 1.5) x $488 = $1220
Now, the additional tax was 5%;
Tax = x 1220 = $61
So, the total cost = New cost + tax = $1220 + $61 = $1281
Answer:
ok
Step-by-step explanation:
slope of abc is similar than cde
3x+1=-14
x=-5
Subtract 1 from both sides.
3x=-15
Finally, divide both sides by 3 to get rid of 3x.
Therefore, we have proved that x=-5.
