The definition of self-service. Self-service is an approach where users access resources to find solutions on their own without requiring assistance from a service representative.
(1) total cost for 10k photos = fixed costs + variable costs = 5500 + 0.15 * 10000 = 5500+ 1500 = 7000
total cost for 25k photos = fixed costs + variable costs = 5500 + 0.15 * 25000 = 5500 + 3750 = 9250
a.(2) total cost for 10k photos = fixed costs + variable costs = 7000 + 0.05 * 10000 =7000+ 500 = 7500
total cost for 25k photos = fixed costs + variable costs =7000 + 0.05 * 25000 = 7000 + 1250 = 8250
b. For this, we first find the volume at which both processes cost the same.
let the required volume be x.
So, 5500 + 0.15x = 7000 + 0.05x
=> 0.15x - 0.05x = 7000 - 5500
=> 0.1x = 1500
=> x = 1500/0.1 = 15,000
So, at the monthly volume of 15,001 photos and above, the proposed process becomes preferable.
