Answer:
I will help with 1) and 2) as they are not right either.
Explanation:
1) 9.6 pound of trail mix at $1.20 per pound means Corrine has spent
= 9.6*1.2
= $11.52 on trail mix
2) Each person completed in approximately 18.1 seconds.
Total relay team finish time = 18.1*4
= 72.4 seconds
I hope that helps!
