Layla spent 25 minutes on
her math homework and
30 minutes on her social
studies homework. Elijah
spent 3 times as much time
on his homework. Which
expression represents the
number of minutes that Elijah
spent on his homework?
A 25 + (30 X 3)
B 25+ 30 + 3
C 3 x 25 + 30
D 3 x (25 + 30)

D

Step-by-step explanation:

25+30= time Layla spent. 3x time layla spent = elijah's time
