How many muffins did Melissa make? ** Melissa made 30 x 4 = <<30*4=120>>120 muffins
How many muffins did Sasha and Melissa make together? ** Together, Melissa and Sasha made 30 + 120 = <<30+120=150>>150 muffins
How many muffins did Tiffany make? ** Tiffany made 150/2 = <<150/2=75>>75 muffins
How many muffins did Sasha, Melissa, and Tiffany make altogether? ** Altogether, they made 150 + 75 = <<150+75=225>>225 muffins
How much money did Sasha, Melissa, and Tiffany contribute to the fundraiser? ** They contributed 225 x $4 = $<<225*4=900>>900 to the fundraiser
