The value of the number in terms of x will be : 11x + 3
Explanation:
In the two digit number tens' digit is x and units' digit is 3 more than x , that means (x+3)
For getting a number, we will first multiply each digit by it's position and then just add all the products.
For x, the position is 10 and for (x+3), position is unit i.e. 1
So, the number will be:
![[x*10]+[(x+3)*1] \\ \\ =10x + x+3\\ \\ =11x+3](https://tex.z-dn.net/?f=%20%5Bx%2A10%5D%2B%5B%28x%2B3%29%2A1%5D%20%5C%5C%20%5C%5C%20%3D10x%20%2B%20x%2B3%5C%5C%20%5C%5C%20%3D11x%2B3%20)

Step-by-step explanation:
Expenditures are negatives do I'd use -42.50
Interest formula: A=P(1 + r)^t
A = 10000(1 + 0.1)^5
A = 10000(1.01)^5
A = 10000(1.0510100501)
A = $10,510.10
Answer:
you have to add them together
