The force F required to stretch a string varies directly with the amount the string is stretched, S. 32 pounds is needed to stretch a string 4 inches..
A) Write a direct variation equation that relates F and S.
Answer: 32=F*S+4 is what I think.. Most likely wrong.
B) How much force is required to stretch a string 20 inches?
Answer: well, first. I would need to have my equation right.
What I think I need help with: Could I please have somebody help me fix my equation so I could solve for B? Cause I don't think my equation is right.
