An expression is shown below: 3(9a+6b)−(5a+2b) Part A: Simplify the expression shown above. Part B: If a represents apples that cost $0.35 each and b represents bananas that cost $0.20 each, what is the total cost based on the expression above?

part a : 3(14a-8b)      

Step-by-step explanation: part a : you add 9a and 5 a since they have the same varible  then you add 6b and 2b to get 8b which gets you your first answer of 3(14a-8b)

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.
