Samantha had 300 beads 30% were black 25% were red 15% were white. the remaining beads are blue. how many were blue?

Hello!

For this you have to find the amount of every color of beads.

300 * 0.30 which is 90 black beads

300 * 0.25 is 75 red beads

300 * 0.15 is 45 white beads

Then you add them.

90+75+45 = 210

Then subtract them from the total

300 - 210 = 90

The answer is 90 blue beads or 30%

Hope this helps!

1. isolate the variable, in this case, d. subtract 35.5 on both sides of the equation.2. 52 subtracted by 35.5 is 16.53. therefore your answer would be d= 16.5this is the basics of pre algebra, isolating variable through adding, subtracting, multiplying, and dividing, if you have any other questions to ask just comment!
