CHAP. CCCXCVI. Of the Exchanges of
Placentia with Lucca.
* 1.1PLacentia doth exchange with
Lucca, and giveth 100 Crowns of Mark, to have in
Lucca po∣sito 117½ Crowns of Livers
7½ per Crown; I demand then, at this rate, for Crowns
406. 10. 10. of Mark how many Crowns of li.
7½ shall I have credit in Lucca? First multiply the said sum of Crowns of Mark by Crowns
117½ per cent. and of the product cut off the two last Figures, which multiplyed by 20, and by 12, to bring them into
Sols and Deniers of Gold, they will make Crowns 477.
13. 8. And so many Crowns of Livers 7½ per Crown shall I have at Lucca•• Example: 〈 math 〉〈 math 〉

* 1.2The proof of this Exchange serveth to know how to make the
account, when Lucca exchangeth with Placentia, being done by the Rule of Three, saying, If Crow. 177½ give 100 Crow. of Mark, how much will 477. 13. 8.
Crow. give? And it will be 406. 10. 10 Crow. of
Mark. And this is to be observed in the proof of the rest, according to former mentioned rules.
