To answer this, you will first need to simply the expressions.
Now with the expressions simplified, you'll add the two together getting 
A = 0.50j + 6.......u r correct
he started with 6....and he is selling each cup (j) for 0.50
so lets say he sold 10 cups...u would sub in 10 for j
A = 0.50(10) + 6
A = 5 + 6
A = 11......and he would have $ 11
Answer:
12^2(Pi)+24*(Pi)*35
Step-by-step explanation:
12^2(Pi)+24*(Pi)*35
Answer:
D. 12²•π
Step-by-step explanation:
Area of a circle = πr²
Radius (r) = ½ of diameter = ½*24 = 12 inches
Plug in the value into the area
Area = π * (12)²
Area = π * 12²
Area = 12²•π
