Answer:

0.5 represent the original 100% but we want to obtain a 75% aditional so we can find for the value x if interest and we got:

So we need to sell the fries ar 0.875$ if we want to obtain a 75% of margin
Step-by-step explanation:
For this case we know that the french fries cost $0.50 and we want to have a margin of 75% on the fries. So we can use the following proportional rule:

0.5 represent the original 100% but we want to obtain a 75% aditional so we can find for the value x if interest and we got:

So we need to sell the fries ar 0.875$ if we want to obtain a 75% of margin

Answer:
The equation is true.
Step-by-step explanation:
Simplify. Combine like terms:
3x + 15 = (2x + x) + (10 + 5)
3x + 15 = (3x) + 15
Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Subtract 3x and 15 from both sides:
3x (-3x) + 15 (-15) = 3x (-3x) + 15 (-15)
3x - 3x = 15 - 15
0 = 0
~ True. The two expressions are equal to each other.
