Jim can do the 1/2 of floor in 4 hours
pete completes 1/2 of floor in 2 hour
therefor, since, pete took 1/2 as much time, pete can tile 2 times as many tiles (logic)
pete can lay 25 more than jim
if pete is 2 times of jim
p=2j
and pete is 25 more than jim
p=25+j
2j=p=25+j
2j=25+j
minus j
j=25
jim lays at 25 tiles per hour
C is answer
Answer:
x=1 y=2
Step-by-step explanation:
Isolate x for 4x -y=2: X=2+y/4
Substitute x= 2+y/4
(2+y/4 )+3y=7
simplify 2+13y/4=7
Isolate y for 2+13y/4=7
y=2
Forx= 2+y/4
Substitute y = 2
x= 2+2/4
Simplify
X=1
