Answer: omggg I need that one too irdk I need help
Step-by-step explanation:
I think it’s the third or second
Since Rosa ends up on the first floor, we'll set the equation equal to 1. We don't know Rosa's floor, so we'll set her floor as the unknown x. When she goes down, we'll subtract from her floor (x) and when she goes up, we'll add.
x= Rosa's floor
down 2= subtract 2
up 7= add 7
down 15= subtract 15
ends up on 1 so equation equals 1
x - 2 + 7 - 15= 1
combine like terms
x - 10= 1
add 10 to both sides
x= 11
ANSWER:
Rosa works on the 11th floor
