Answer
# Answer:
$1444.50\times(1 + 0.02+0.15)$
# Explanation:
## Step1: Calculate shipping cost
The shipping cost is 2% of the total cost of computer - repair. So the shipping cost is $1444.50\times0.02$.
## Step2: Calculate gratuity cost
The gratuity is 15% of the total cost of computer - repair (excluding shipping, but here we can calculate it based on the repair cost first). The gratuity cost is $1444.50\times0.15$.
## Step3: Calculate new total cost
The new total cost is the sum of the original repair cost, shipping cost and gratuity cost. We can factor out the original repair cost $1444.50$. So the new total cost is $1444.50\times(1 + 0.02+0.15)$.
