On September 22, Illuminations Lighting Center sold $6,400 in merchandise on account to Sunshine Builders, a charge customer. A 5% sales tax applied to the sale. The date of the sales slip was September 22, and the credit terms were 2/10, n/30. What is the last day Sunshine Builders can pay the invoice and still receive a discount?

1st of October is the last day discount would be given if payment is received

Step-by-step explanation:

2/10 means that a discount rate of 2% would given to the buyer if he or she pays within next in ten days otherwise full amount is expected in 30 days i.e n/30.

The discount would be available if payment is made between September 22 and October 1st

In essence,the last day Sunshine Builders can pay the invoice and still receive a discount is 1st October

i think it's either c or d

step-by-step explanation: the entire question is extremely odd. 04 obviously refers to the interest rate. honestly i will say the answer is c. because the (2 x 12) part would mean it's compounded semiannually. i'll say choose c.
