Answer 1

Answer:

a. 12 cups - 2 * n cups b. 2 * (6-n) cups

Step-by-step explanation:

a.

we start with 12 cups of flour

we subtract 2 cups of flour for each baking cycle

thus, cups of flour = 12 cups - 2 cups for each cycle

2 cups for each cycle = 2 cups * number of cycles = 2 cups * n

cups of flour = 12 cups - 2 * n cups

b.

note that 12 is a multiple of 2 -- 2 * 6 = 12

thus, 12 cups = 2* 6 cups

cups of flour = 12 cups - 2 * n cups = 2 * 6 cups - 2 * n cups

factor out the 2

cups of flour = 2 * (6-n) cups
