Answer 1

help

Answer 2

call the unknown price x
they say
the price (i.e. x) plus 20% of x adds up to 1.50

Answer 3

20% is the same as 20/100 or 0.2 as a decimal
x + 0.2x = 1.50
or
x * 1.2 = 1.50
I would divide both sides by 1.2 to find out what x is

Answer 4

1.25

Answer 5

is that right @phi

Answer 6

yes. you can check by finding 20% of 1.25
0.2*1.25= 0.25
if we add this to the price: 1.25 + 0.25 = 1.50
we get the Oct price.

looks ok
