To find the total cost of the order, we need to set the expression equal to the total cost. Given the equation you provided:
\[ 0.75s + 0.5p = \text{Total Cost} \]
Where:
- \( s \) is the number of packets of sunflower seeds at $0.75 each,
- \( p \) is the number of packets of pumpkin seeds at $0.50 each.
To complete the equation, you'll need to determine the numerical value for the total cost based on the specifics of the problem, like how many packets of sunflower and pumpkin seeds are being purchased.
If the problem states a specific total cost, you would replace "Total Cost" with that specific amount. For example, if the total cost is $10, then the equation would be:
\[ 0.75s + 0.5p = 10 \]
So, make sure to insert the correct total amount based on the given problem details.
