Answer:
(a) $3,444,444.44
(b) $11,160,000
Explanation:
(a) Effective purchasing power:
= Loan amount ÷ (1 + cumulative inflation rate)
= $6,200,000 ÷ (1 + 0.80)
= $6,200,000 ÷ 1.80
= $3,444,444.44
Therefore, the effective purchasing power of the $6,200,000 is $3,444,444.
(b) Lender should be repaid:
= Loan amount × (1 + cumulative inflation rate)
= $6,200,000 × (1 + 0.80)
= $6,200,000 × 1.80
= $11,160,000
