1. What value appears if the formula [tex]$=A2+B2$[/tex] is entered in C2?

A. 23

[tex]\[
A2 + B2 = 20 + 3 = 23
\][/tex]

2. What formula should be used to find a [tex]$15\%$[/tex] tip on the [tex]$\$[/tex]30$ bill in cell A3?



Answer :

Sure! Let's address the questions step-by-step.

### 1) Calculating the Value in Cell C2

We are asked what value appears if the formula `=A2+B2` is entered in cell C2. Let's break this down:

- Given Values:
- [tex]\( A2 = 20 \)[/tex]
- [tex]\( B2 = 3 \)[/tex]

- Formula:
- [tex]\( =A2 + B2 \)[/tex]

To compute this, we simply add the value of cell A2 to the value of cell B2:
[tex]\[ A2 + B2 = 20 + 3 = 23 \][/tex]

Therefore, the value that appears in cell C2 is 23.

### 2) Finding the Formula for a 15% Tip on a [tex]$30 Bill in Cell A3 We are asked what formula should be used to find a 15% tip on the $[/tex]30 bill located in cell A3.

- Given Value:
- [tex]\( A3 = 30 \)[/tex]
- Tip percentage = 15%

To find 15% of a value, we can multiply the value by 0.15 (since 15% as a decimal is 0.15):
[tex]\[ \text{Tip} = 0.15 \times A3 \][/tex]

- Calculation:
- [tex]\( 0.15 \times 30 = 4.5 \)[/tex]

So, the formula that should be used to find a 15% tip on the [tex]$30 bill in cell A3 is: \[ = 0.15 * A3 \] Thus, the 15% tip on a $[/tex]30 bill is 4.5.

Combining these:

1) The value from entering `=A2+B2` in cell C2 is: 23
2) The formula to find a 15% tip on a $30 bill in cell A3 is: `=0.15*A3`

And the result of the formula in step 2) is: 4.5
