Because the first payment is due today and the remaining payments are monthly, this is an annuity-due problem. Use the annuity-due present-value formula.

1) Key concepts
- Periodic rate r = APR/12 because interest is compounded monthly.
- Number of payments n = years × 12.
- Present value of an annuity due: PV = PMT × [(1 − (1 + r)^−n)/r] × (1 + r). Equivalently PV = first payment (at t=0) + PV of the remaining (n − 1) payments treated as an ordinary annuity.

2) Step-by-step calculation
- PMT = $375
- APR = 7.08% so monthly rate r = 0.0708/12 = 0.0059 (0.59% per month)
- n = 3 years × 12 = 36 payments

Using the annuity-due formula:
(1) Compute (1 + r)^36. With r = 0.0059, (1.0059)^36 ≈ 1.2358703.
(2) Compute its reciprocal: (1 + r)^−36 ≈ 0.8088367.
(3) Compute the ordinary-annuity factor: [1 − (1 + r)^−36]/r ≈ (1 − 0.8088367)/0.0059 ≈ 0.1911633/0.0059 ≈ 32.4006.
(4) Convert to annuity-due by multiplying by (1 + r): 32.4006 × 1.0059 ≈ 32.53899.
(5) Multiply by PMT: PV ≈ 375 × 32.53899 ≈ $12,202.12.

(Alternative decomposition: PV = 375 + 375 × [1 − (1.0059)^−35]/0.0059 gives the same result to rounding.)

3) Intermediate steps shown above (exponents, reciprocals, divisions, and multiplications) are the arithmetic used to reach the PV.

4) Why this answer is correct
- The annuity-due formula accounts for the immediate first payment (t=0) by multiplying the ordinary-annuity factor by (1 + r), which increases PV slightly versus an ordinary annuity. Plugging in the exact monthly rate and 36 months yields $12,202.12.

5) Why the other choices are incorrect
- $12,130.55 and $11,792.84 are too low; they would result from treating the stream as an ordinary annuity or using a slightly different rate/term.
- $12,627.07 is too high; it overstates the PV (equivalent to using a much smaller discount rate or more payments).

Conclusion: The correct present value of the lease payments today is $12,202.12, matching the provided correct answer.
