The spanish club decides to sell school pins $1.50 each and t-shirts at $6.50 each for a fundraiser. they projects that they will sell 20 school pins and five t-shirts each week for three weeks how much money are they projecting to make during the fundraiser

Ok so 1.5 is pins and 6.5 is t shirts so you multiply 1.5 x 20 and 6.5 x 5 so for pins= $30 and T-shirts= $32.50 and you times both those numbers by 3 so for pins you get $90 and T-shirts you get $97.50. Finally you add them and get $187.5 so the answer is $187.5 for the project.

The answer is that the rate of change is $50 per 1 monthhope this ; )
