I think ( b) is non proportional linear
<u>Answer:</u>
BC = 18 cm
<u>Step-by-step explanation:</u>
As we can see from the diagram:
AB + BC + CD = AD
⇒ 10 cm + BC + 11 cm = 39 cm
⇒ BC + 21 cm = 39 cm
⇒ BC = 39 cm - 21 cm
⇒ BC = 18 cm
Well if the increase is 135% then
actual price=85
135% of actual price=114.75
new price
= actual price + increased price
= 85+114.75
=119.75
