To find the total cost \( c \) of buying 5 slices of pizza, we can set up the equation based on the price per slice and the number of slices purchased. Since each slice costs $1.95 and you are buying 5 slices, the equation can be represented as:
\[ c = 1.95 \times 5 \]
To express this mathematically:
\[ c = 5 \times 1.95 \]
Thus, the correct equation that represents the total cost is:
\[ c = 5 \times 1.95 \] or simply \( c = 9.75 \).
Therefore, none of the provided responses are correct as they do not accurately represent this relationship. However, to select the most relevant option from what is provided, you would need to rewrite the correct relationship:
Based on what you've provided, there seems to be no option that matches this equation exactly, but the equation you are looking for would most closely align with a linear equation representation.
If only choosing among your options, the first one can be considered the appropriate format for noting the relationship, rewritten correctly to represent the equation using multiplication.
The best way to write it mathematically to represent total pizza cost correctly would be:
\[ c = 1.95 \times 5 \]
It can't be directly taken from your options.
