Olivia was supposed to make a payment of $4,500 in 3 years and another payment for $1,600 in 4 years to Loon Company as part of a payment plan. Instead, he is trying to reach an agreement with the company where he would pay an upfront amount now, and an amount of $900 in 6 years. Assume that money is worth 5.28% compounded quarterly.

a. Calculate the equivalent value of the $4,500 payment and the $1,600 payment today.

b. Calculate the upfront amount that he should pay under the alternative payment agreement so that the payments are equivalent.
