Answer:
look at the picture i sent.......
It's Positive slope because it's the opposite
We have an equation: 250/?= 50/100
Cross multiply:
50*?= 250*100
⇒ ?= 250*100/50= 500
The number is 500~
We have another equation: ?/500= 80/100
Cross multiply:
100*?= 80*500
⇒?= 80*500/100= 400
80% of 500 is 400~
