If you're not including tax, here's how you will do it:
15% can be converted to .15
you would then multiply .15 by 75.50
.15 * 75.50 = 11.325
since you can't give someone half of a penny, you must round up, getting 11.33
now you add 11.33 to 75.50
11.33 + 75.50 = 86.83
so, her bill would come out to be $86.83
Don't forget the "$" sign!

Answer:
28
Step-by-step explanation:
8-(-4)+9-(-7)
The answer is 6. We can figure this out by using
Brackets
Indices (exponents or powers)
Division
Multiplication
Addition
Subtraction
Note: Division and multiplication are equal in value, you solve an equation or expression based on its placement from left to right.
Addition and Subtraction follow the same principles as Division and Multiplication.
Anyways, BIDMAS is made to help us remember in which order we do an equation or expression. Brackets first, then Indices etc.
Moving on, we have an expression here:
4 + (9 x 2) / (4 - 1) - 4
First, we will complete the brackets, which will simplify the equation to:
4 + (18) / (3) - 4
Then, we can remove the brackets and move onto the division. Doing the division will make the expression look like this:
4 + 6 - 4
All that is left to do is to subtract and add. Therefore, the simplest form of this expression is 6, as the + 4 and - 4 would cancel out.
Answer: 6
1,334.8 m^2 is the correct answer.
Repeaterd use of figures of one kind or more to cover a plane without gaps and without overlaps is called tessellation.
only equilateral triangles squares and regular hexagons can form tessellation.
it is because each of their interior angles should be a factor of 360°. only these 3 kinds satisfy this.
