Question

the company also discovered that it costs$28 to produce 2 camera cases. $50 to produce 4 camera cases, and $140 to produces 10 camera cases.find the total cost of producing 12 camera cases.

Answer 1

$28 for 2 cases or $140 for 10 cases means $14 per case
cost of producing 12 = option 1 (10 + 2 ) = 140 + 28 = $168 option 2 12 * 14 = $168

$50 for 4 cases means 50/4 = 12.50 per case
12 cases at 12.50 each = $150
option 2 12/4* 50 = 3 * 50 = $150

"the company also discovered" means there is more to this problem and this will help to determine what rate to use to find the true cost of producing 12 cases

do you have the rest of the problem?
