Question

The final cost of an item was $50. This included 6% sales tax. What was the price of the item before tax?

Answer 1

47

Answer 2

oh no!

Answer 3

x + 0.06x = 50
1.06x=50
x= 47.17

Answer 4

to increase a number by 6% multiply it by 1.06

Answer 5

so you know
\[1.06P=50\] and therefore
\[P=50\div1.06\]

Answer 6

50 = X + 0.06*X

Answer 7

you cannot take 6% of 50 and subtract because 6% of 50 is more than 6% of the original price

Answer 8

you can of course also start with
\[50=P+.06P\] but then by the distributive law you know that this is the same as
\[50=(1.06)P\] so easiest to start with
\[1.06P=50\]
