Given equations:
P=w+2
p=7w-16
Compare both equations
7w-16=w+2
Add 16 to both sides.
7w=w+18
Subtract w from both sides.
6w=18
Divide both sides by 6.
w=3, which is the age of Winnie.
Now Peter's age=3+2=5 years
Option A is the correct method to find the age of Peter and Winnie.
25% of 30 can be found by converting 25% to a decimal and multiplying it by 30.
25% = 0.25
30x0.25=7.5
So x is 7.5.
