If she will buy 35 t-shirts, 45 pairs of shorts, and 25 windbreakers, what will be her total cost?

It is 973.75.

Step-by-step explanation:T-shirt cost $7.50 each short cost nine dollars each windbreaker cost $12.25 so if she wants to buy 35 T-shirts that is 35 times $7.50 which is $262.5 if she wants to buy 45 Shorts that is 45×9 dollars which is $405 if she wants to buy 25 hamburgers that is 25 times $12.25 which equals out to $306 and 25 cents. So in total you add $262.5 plus $405 plus $306 which equals out to a total of $973.75. I hope that answers your question and you’re welcome.
