Answer:
3 - (n - 1) = 1/2(3n - 4)
Step-by-step explanation:
We want to write three minus the difference of a number and one equals one-half of the difference of three times the same number and four as an equation.
Let the number be n.
The first part is: three minus the difference of a number and one:
3 - (n - 1)
The second part is: one-half of the difference of three times the same number and four:
1/2(3n - 4)
Now, let us equate the first and second parts:
3 - (n - 1) = 1/2(3n - 4)

Answer:
55%
the percent decrease of the sale price from the regular price is 55%
Step-by-step explanation:
Percentage decrease is the percentage change in the sales price (regular and new)
Percentage decrease %∆P = ∆P/Pr × 100%
∆P = change in sales price = $135 - $60.75
Pr = regular price = $135
Substituting the values;
%∆P = (135-60.75)/135 × 100%
%∆P = 55%
the percent decrease of the sale price from the regular price is 55%
