Answer:
40 pounds
Step-by-step explanation:
First you have to make an equation for each senario. For Peters, it would be 0.35n (n is the amount of pounds), Freddys it would be 0.10n+10. Freddys is like that because the flat rate of $10 and they charge $0.10 per pound. Then you set them up to equal each other. 0.35n=0.10n+10. Now you want to get n by itself, so you would write it like this 0.35n-0.10n=10, it would simplify to 0.25n=10. Divide both sides by 0.25 to get your answer of 40 pounds.
