2) Penelope warmed up for volleyball practice for a total of 5 minutes by doing butt kicks
and toe touches. She did 5 butt kicks per second and 2 toe touches per second.
Penelope did butt kicks for y seconds before switching to toe touches. She incorrectly
used the algebraic expression 5y + 2(5 - y) to represent the total number of butt kicks <4 and toe touches she did for her warmup. Correct the algebraic expression.
