The price of the jacket in decimals is $ 41.89
The decimal numeral system is widely used to express both integer and non-integer numbers.
- The Hindu-Arabic number system has been expanded to include non-integer values. The term "decimal notation" is used to refer to the way that numbers are represented using the decimal system.
- The decimal system has been developed to represent any real number in an endless number of decimals by using any number of digits after the decimal separator (see decimal representation).
- Since there are only a few non-zero digits beyond the decimal separator, the decimal numerals in this context are sometimes referred to as terminating decimals.
- An unending decimal that, at a given point, continues to use the same set of digits repeatedly is said to be recurrent.
Let the price of the jacket be x.
Price of the pair of shoes = x + 7.65
Total cost of both the pieces = x + x + 7.65 = 2x+7.65
But the total cost is $91.43
Hence forming a linear equation we get :
$91.43= 2x+7.65
solving the linear equation for x we get :
x=$ 41.89
hence the cost of the jacket is $ 41.89 .
