1. ## Interest

A person wants to buy a set of upholstered worth seeing for $3,500.00. To finance it in 4 equal installments without input, each service will cost U.S.$ 930.36. If, however, one of them is given as input, the value of other benefits reduced will to R \$ 907.67.

The monthly rate of compound interest used in this funding is:
a) 0,50 %
b) 1,00 %
c) 1,50 %
d) 2,00 %
e) 2,50 %

The answer is 2,50%. I find 1,5%

2. Do you know someone who could rewrite your problem in clear English?
"Input, service, benefit" are terms/words strange to loan calculations...
