Answer 1

All you have to do is one by one add or subtract the numbers so if you add 2.25 to 40.75 you get 43 after that subtract 1.75. After that you get 41.25. Subtract 0.25 you get 41. Then add 3 you get 44. You add 1.75 to that and get 45.75

Answer 2

$45.75

Explanation:

1. Set up the equation: 40.75 + 2.25 - 1.75 - 0.25 + 3 + 1.75 = x

You want to include the amount that she started with which is $40.75 . In this case x is the total amount of money that Samantha has by the end of the week. If Samantha loses money on a certain day you will subtract it, whereas if she gains money you will add it.

2.Simplify: 43 - 1.75 - 0.25 + 3 + 1.75 = x

I just added the 1st two numbers. You can just type this into the calculator if you are comfortable with that or you can solve this by adding and subtracting the numbers on a piece of scratch paper.

3. Simplify: 41.25 - 0.25 + 3 + 1.75 = x

4. Simplify: 41 + 3 + 1.75 = x

5. Simplify: 44 + 1.75 = x

6. Simplify: 45.75 = x
