Sandra has a collection of beads. Of all the beads, 2/3 are red, 1/4 are pink, and the rest are white. There are 28 more red beads than white beads. How many beads does Sandra have altogether? (PLEASE SHOW STEPS!)
Let x be the total number of beads. Red beads: 2/3*x Pink beads: 1/4*x White beads: x-2/3x-1/4x = 12/12x-8/12x-3/12x = 1/12x Using the 28 more, you get the equation Red -28 = White Substituting x for each, you get: 2/3x - 28 = 1/12x 8/12x - 28 = 1/12x 7/12x = 28 1/12x = 4 x = 48 beads in total
