We're not given the choices but we don't need them.
The only way this problem is tractable to a middle or high schooler is if the polynomial is perfect cube; a little thought yields
To find the inverse let's call f(x) x and call x y and solve for y.
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
