I would not use a table, because the expressions and equation easily enough to form without making a table
Or, at least easier for me.

%28costaricancoffee%29%2F%28mixture%29=fractionAsCostaricancoffee---THIS is why I would not use a table.

%2815%2B%280.05%29%2A210%29%2F%2815%2B210%29=fractionAsCostaRicanCoffee

%2815%2B10.5%29%2F225

25.5%2F225

0.113333333. the fraction as repeating decimal.

highlight%2811%261%2F3%29 percent Costa Rican Coffee
