During a sale, all prices were reduced by 15%. A jacket that was bought for $55. Calculate the original price of the jacket. An extract from MS Neto's bank statement for the month of May is shown below. Calculate the value of X. Calculate the value of Y.

Set up the equation.

The original price of the jacket was \boxed{\mathbf{\64.71}}$.

b) i) To calculate the value of $X$:
$X$ represents the bank charges of 1% on the current account balance before the charge. The balance before the charge was $412.00 (after the salary was credited).

$X = 1\% \times \$412.00$

The value of $X$ is \boxed{\mathbf{\4.12}}$.

b) ii) To calculate the value of $Y$:
$Y$ is the account balance after the bank charges ($X$) have been debited from the previous balance of $412.00.

$Y = \$412.00 - X$ $Y = \$412.00 - \$4.12$ $Y = \$407.88$ The value of $Y$ is \boxed{\mathbf{\407.88}}$.
