Your French fries have a food cost of $0.50, and you want to have a margin of 75% on the fries. What will the final selling price be?

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

in simplified version   it would be x ≤-4

step-by-step explanation:

multiply each term in x ≤-4 by -1
