Answer:
Cost of selling price = $5.33 (Approx)
Step-by-step explanation:
Given:
Cost of price of cookie = $3 each
Number of cookies = 80
Damaged = 10%
Markup on cost = 60%
Find:
Cost of selling price
Computation:
Total cost of cookie = 80 × 3 = 240
Markup price = 240 + 240(60%)
Markup price = 384
Number of damage cookies = 80(10%) = 8
Remain cookies = 80 - 8 = 72
Cost of selling price = Markup price / Remain cookies
Cost of selling price = 384 / 72
Cost of selling price = $5.33 (Approx)
Answer:
Function: 
Not Function: 
and 
Step-by-step explanation:
Given
Required
Determine if 
is a function of 
Solving x+y=9
Make y the subject of formula
<em>Hence; y is a function of x</em>
Solving
Subtract x² from both sides
Square root of both sides
This implies that
or 
<em>Because </em><em> can be any of those two expressions, it is not a function.</em>
Solving
Reorder
Take square roots
This implies that
or 
<em>Because </em><em> can be any of those two expressions, it is not a function.</em>
