10) The cost of producing Iphones can be linearly related to the number of Iphones produced. If 100 Iphones are produced the cost is $102,500 and If 2000 iphones are produced the cost is $150,000.

Part A: Find the equation for the cost of producing Iphones.

Part B: Due to the mass production of Iphones, Apple has noticed a perpendicular decline in Ipods in relation to Iphones.
Find the equation that shows this decline If 100 Ipods are produced for the cost of $120,000.

Part C: A sister company wants to create a knock off iphone using a model that is parallel to Apple's iphone production,
However, their production is significantly less expensive. They can produce 1000 knock off iphones at the cost is
$25,000. Find the equation for the cost of producing knock off iphones.
