To calculate the selling price, we need to add 70% of the cost to the cost. This can be done using the following formula:
selling price = cost + 0.7*cost = 1.7*cost

Using this formula, we can calculate the selling price for each item:
- Item 1: 1.7*1.5 = $2.55
- Item 2: 1.7*2.7 = $4.59
- Item 3: 1.7*5.2 = $8.84
- Item 4: 1.7*13 = $22.10
- Item 5: 1.7*17.7 = $30.09

Therefore, option B is the best choice as it provides the correct selling prices for each item.
