Jennifer set up 15 rows of chairs in the cafeteria for her school's talent competition. In the
first 10 rows, she set up 30 chairs on the left side of the middle aisle and x chairs on the right
side. In the last 5 rows, she set up 20 chairs on the left side of the middle aisle and y chairs
on the right side to make room for the sound crew.
Pick all the expressions that represent how many chairs Jennifer set up.
(300 + 10x) + (100 +5y)
30(x + 10) + 20 (y + 5)
10(30 + x) + 5 (20 + y)
x(10 + 30) + y(5 + 20)
