To calculate the total cost of the fabric Jake needs to purchase, you can multiply the amount of fabric (in yards) he needs by the cost per yard.
The total cost can be calculated as follows:
\[ \text{Total Cost} = \text{Amount of Fabric} \times \text{Cost per Yard} \]
Substituting the numbers:
\[ \text{Total Cost} = 7.6 , \text{yards} \times 12.85 , \text{dollars/yard} \]
Now, perform the multiplication:
\[ 7.6 \times 12.85 = 97.46 \]
Therefore, the total cost of the fabric Jake will purchase is $97.46.
