Josh and Anthony have a lemonade stand.They charge $1 for 2 cups of lemonade.They sell 14 cups each afternoon.Is it reasonable to say Josh and Anthony earned more than $50 after 3 afternoons?
Answers
No it is not, whatsoever.
$1 for 2 cups. 14 cups in an afternoon means they got $7. If they did this for three days (7 x 3) they'd have 21 dollars. it is not reasonable because 21 is nowhere near 50.
Hope this helps

How do you solve equations that contain addition or subtraction?
Answers
Any equation given, with a variable, could be solved by applying the inverse operation.
Example:-
4 + x = 8 -4 -4
x = 8 -4 x = 4
Answer; x = 4
To learn the basics I would suggest using this simple model to solve. Remember, that you can add, subtract, multiply, or divide anything to both side of the equal sign. Ex. 5 + 5 = x -5 -5
Now, let's try a real problem:
10 + x = 15 Now, I know this may seem to be an easy problem, but by using the method I am about to show you, you will be able to solve any addition, subtraction, even multiplication, and division equation! This would be how you solve: 10 + x = 15 -10 -10 ---------------------------------------- x = 5
