If 30 is increased by 20%, what is the new amount?

The new amount is 36

Step-by-step explanation:

we know that

100%+20%=120%

Let

x> the new amount

The number 30 represent the 100%

so

by proportion

30/100%=x/120%

x=120*30/100=36

y-y1=4(x-x1)

step-by-step explanation:

this is point-slope form since you only have 4 as the slope it goes in place of m
