To find out how much Tanveer paid for 0.7 pounds of sliced ham at $6.79 per pound, you can multiply the weight of the ham by the cost per pound:
\[ \text{Total cost} = \text{Weight} \times \text{Cost per pound} \]
\[ \text{Total cost} = 0.7 , \text{pounds} \times 6.79 , \text{dollars/pound} \]
Now, calculating:
\[ \text{Total cost} = 0.7 \times 6.79 = 4.753 \]
Rounding this value to two decimal places, Tanveer paid approximately $4.75.
So, the answer is \( \text{ } \boxed{4.75} \).
