Alyssa went shopping for new accessories for fall. She bought 4 new scarves for $15 each and 4 bracelets that each cost the same amount. She used a coupon for $10 off. How much did each bracelet cost if she spent $73.40 total? Which would be the appropriate equation to solve this? Group of answer choices 4(10) + 15 + b = 73.40 4(15) + b -10 = 73.40 4(15 + b) - 10 = 73.40 4(15 + b -10) = 73.40
