Step-by-step explanation:
Expanded notation may be defined as the way of expressing a number by exhibiting its value of each of the digit.
In an expanded notation, the number is always represented as a summation of each of the digit times its place value, while in the expanded form, an addition is used between the place value numbers.
A number containing zero can be written in the expanded form as for example,
509,300
Since digit 5 is 100,000th place, 9 is in 1,000th place and the digit 3 is 100th place, the number can be written as --
5 x 100,000 + 9 x 1,000 + 3 x 100
The selling price will be $232 if he applies a 45% markup.
Step-by-step explanation:
Cost of each stereo = $160
Mark up = 45%
Amount of mark up =

x+ y = 96 → y = 96 - x (1)
And the price per plain cake * the number he sold + price of the decorated cake * the number he sold = total sales
So
8x + 12y = 800 (2)
Subbing (1) into (2), we have that
8x + 12 (96 - x) = 800 simplify
8x + 1152 - 12x = 800
-4x + 1152 = 800 subtract 1152 from both sides
-4x = -352 divide both sides by -4
x = 88 = the number of plain cakes he sold
And 96 - x = 96 - 88 = 8 = the number of decorated cakes he sold
