please help im really struggling. thanks

Use this data to answer the next 5 questions (Questions 46- 50). The Philly Bike Shop sells a matching pair of medium-end lights - a headlight and a taillight. Both lights are made by the same supplier. The supplier sells each light of either type for $20. The Philly Bike Shop's cost of holding inventory for these lights is 20% of the product cost per year. The demand for either type of lights is 5,000 units per year. If the Bike Shop decides to order each light type separately, and then bundle it in store, the supplier charges a flat fee of $100 for each order delivery, regardless of the light type. If the Bike Shop decides to order the two lights together, then the supplier charges a delivery fee of $100 and an additional fee of $28 for bundling, on every order. Question 46 1 pts If the Philly Bike Shop decides to order each type of light individually, how many units should be in each order, for either type? O 200 and 300 O 400 and 700 O 500 and 500 O 250 and 250 Question 47 1 pts If the Philly Bike Shop decides to order each type of light individually, what is the TRC for the two types of lights, considered together annually? (Hint: It's the same for each type, so calculating one will easily give the total.) O $1,000 each, $2,000 total O $2,000 each, $4,000 total $4,000 each, $8,000 total O $500 each, $1,000 total Question 48 1 pts If the Philly Bike Shop decides to order the two types of lights in an aggregate order, what will be the combined order size? D Question 49 1 pts If the Philly Bike Shop decides to order the two types of lights in an aggregate order, what is the TRC for the two types of lights, considered together annually, in dollars? I pts From the total relevant cost perspective, is it better to order separately or together? O Together O Separately O Cannot be determined
