If you want to make 12 cookies (one dozen), you would use 3/8 cup of sugar because the original recipe requires twice that amount of sugar and also makes twice that amount of cookies.
        
             
        
        
        
Answer:
7) x + 0.09x, where x is the price of the car
8) x + 0.05x where x is the price of clothing
9) It will take michael about 9.14 minutes to eat 32 cookies.
Step-by-step explanation:
7) 9% of x is the same as 0.09x, so you can write this:
x + 0.09x, where x is the price of the car
8) same thing for this one
x + 0.05x where x is the price of clothing
9) michael can eat cookies at a rate of 21 cookies per 6 minutes, or 
Because he will be eating them at the same pace, you can write an equation and solve for the variable:
 =
 = 
cross multiply the proportion:
21 × y = 32 × 6
solve:
21y = 192
y ≈ 9.14
It will take michael about 9.14 minutes to eat 32 cookies.
This works because they both simplify to 3.5 cookies per minute 
 = 3.5
 = 3.5
 = 3.5
 = 3.5
