Step-by-step explanation:
40x + 80 < 400
40x < 320
x < 8
original price of first typewriter = x
2970/x = 110/100
x = 2970 x 100/110 = 2700
Price of first typewriter = Rs 2700
Original price of second typewriter = y
2970/y = 90/100
y = 2970 x 100/90
y = 3300
Original price of second typewriter = 3300
profit from first typewriter = 2970 - 2700 = 270
Loss from second typewriter = 3300 - 2970= 330
270 less than 330
so he lost 330 - 270 = Rs 60 in whole transaction
Answer:
Step-by-step explanation:
m=marta's rope
d=dilbert's rope
3d-10=m
m+d=120
Then you can substitute equation 1 into the second one
(3d-10)+d=120
3d-10+d=120
4d-10=120
4d=130
d=32.5
m+d=120
m+32.5=120
m=120-32.5
