Answer:
cost to afford to bring these calculators is $8.4
markup on retail = 5.6
Step-by-step explanation:
given data
selling price = $14
mark up on selling = 40% = 40/100 = 0.40
to find out
What cost can Mike afford to bring these calculators
solution
we calculate markup on retail that is mark up on selling of selling price
markup on retail = 0.40 × 14
so
cost to afford to bring these calculators = 14 - 5.6
(2.5, - 10 )
given endpoints (x₁, y₁ ) and (x₂, y₂ ) then the midpoint is
( , )
here (x₁, y₁ ) = (- 16, - 12 ) and (x₂, y₂ ) = (21, - 8 ) , then
midpoint = ( , ) = ( , ) = (2.5, - 10 )
