Answer:
D. 12.25x +3.99 = 77.49
Explanation:
We don't know the amount of shirts Mrs. Garfield order, so we can assume that the amount of shirts is x.
We know the amount per shirt, so we can assume the total cost for the shirts is 12.25x
The problem also explained that there was a 3.99 shipping cost, so our equation would look like this.
12.25x+3.99
Lastly, we are told the total cost of the shipment. The total cost is 77.49. Since, 12.25x+ 3.99 is supposed to be the same as 77.49, the equation should look like this.
12.25x +3.99 = 77.49
Final Equation:
12.25x +3.99 = 77.49
This is the same answer as D. on the worksheet.
