Let x = the original price.
Then 1/3 x - 27 = 54
1/3x = 54 + 27 = 81
x = 81 / 1/3
x = 81 * 3
x = $243 (answer).

Answer:
Gradient: m = 3
Step-by-step explanation:
m = change in y/change in x
m = 
m = 
m = 12/4
m = 3
I think it would be C because the equation is y=7x. y=7x is also equal to x=1/7y. If y=45.50, then you would have to divide y by 7, which would equal 6.5.
