Answer:
That would be approximately 4.47.
267 x 0.02 = 5.34
267 + 5.34 = 272.34
267 x 0.08 = 21.36
267 - 21.36 = 245.64
267 + 272.34 + 245.64 = $784.98
The rate of change in z at (4,9) as we change x but hold y fixed is =
3/[2sqrt(3x+2y)] put x = 4 , y = 9 = 3/[2sqrt(12+18) = 3/[2sqrt(30)] The
rate of change in z at (4,9) as we change y but hold x fixed is =
1/sqrt(3x+2y) put x = 4, y =9 = 1/sqrt(30)
Answer:
Markup: $9 ; Selling Price: $24
Step-by-step explanation:
The store makes a profit of $15, to find the mark up of 60%, multiply 15 x 60%.
15 x 0.6 = 9
Add the markup price to the original price.
9 + 15 = $24
The selling price is $24
