It would take him 5 weeks. why?
7.89*20= $156 per week
156*5 weeks= $780
If he took 5 steps forward and then 5 steps backwards he would be at his starting position
5 bc it’s multiplied by x
Hey there!
Let us take Michael's score as ' x '
Let us take Kathryn's score as ' y '
Michael - 70 less than twice Kathryn's
x = 2y - 70
y = y
Add them, we get , 425
2y - 70 + y = 425
3y - 70 = 425
3y = 495
y = 495/3
y = 165
Kathryn's score = 165
Michael - 2 ( 165 ) - 70
= 260
Hope it helps!
