Step 1:Let's solve this step by step:
Step 2:: Identify the base amount
The base repair cost is $$380.75
Step 3:: Calculate the sales tax
The sales tax rate is $$7.5\%$$, which means we need to multiply the base amount by $$0.075
380.75 \times 0.075 = 28.56
Step 4:: Add the sales tax to the base amount
380.75 + 28.56 = 409.31
Step 5:: Round to a reasonable estimate
Looking at the options, the total of $$410$$ is a very close and reasonable estimate for the total amount paid.
Step 6:: Verify the calculation
- Rounded estimate: $$410
- Sales tax: 28.56
Final Answer
410 is a reasonable estimate for the total amount Romeo paid to repair his car, including sales tax.
