Final answer:
To multiply 50 by $8.90, use the formula d3 * e3. This will give you the multiplication of the two values and the result will be displayed in the cell where you enter this formula.
Step-by-step explanation:
To multiply 50, which has been entered in cell d3, by $8.90, which has been entered in cell e3, you should use the formula d3 multiplied by e3. So the correct formula is d3 * e3. This will give you the multiplication of the two values and the result will be displayed in the cell where you enter this formula.
If you want to multiply 50, which has been entered in cell D3, by $8.90, which has been entered in cell E3 on a spreadsheet application such as Microsoft Excel, you should use the formula D3*E3. This formula will output the product of the values in cells D3 and E3 which, in this case, is 50 multiplied by 8.90.
Other calculators may have different inputs requirements, but in a spreadsheet, you simply use the multiplication operator (*) to multiply two cells together. This is different from using scientific notation or exponentials where you would apply different rules, such as adding exponents or moving decimal points when working with powers of 10.
