Charlotte has 30 beads. She has 8 more red beads than blue beads. Which equation represents this situation?
n+ 8n = 30, where n is the number of blue beads
n+ 8n = 30, where n is the number of red beads
n+ (n + 8) = 30, where n is the number of red beads
n+ (n + 8) = 30, where n is the number of blue beads
