Julia owns a coffee shop. she experimented with mixing city roast colombian coffee that costs $7.80 per pound with french roast colombian coffee that costs $8.10 per pound to make a 20-pound blend. her blend should cost her $7.92 per pound. how much of each type of coffee should she buy?

Step-by-step explanation:

x = City Roast Colombian coffee

y = French Roast Colombian coffee

x + y = 20

answer set (b) 0.5, 3/4 80% is in order from least to greatest.  

step-by-step explanation:

in order to compare rational numbers to each other, it is much easier if they are in the same form.   typically, the best form in which to evaluate rational numbers is in decimals.   in order to convert a percent to a decimal, you would divide the given percentage by 100.   you can also accomplish the conversion by moving the decimal point over two places to the left.   for example, the decimal value of 80% is 80/100, or 0.8.   in order to convert a fraction to a decimal, you need to divide the numerator by the denominator.   for example, 3/4 is 0.75.   so, for choice (b) 0.5 3/4 (0.75), 80% (0.8) is the only choice in which the numbers are in order from least to greatest.
