Question

Which equation can be used to find the answer?

Luna sells bracelets at the county fair. So far she has sold 23 bracelets and has 112 left. How many bracelets did she have before selling any?

A.
b ÷ 2 = 23
b = 46
46 bracelets

B.
b ÷ 2 = 112
b = 224
224 bracelets

C.
b + 23 = 112
b = 89
89 bracelets

D.
b – 23 = 112
b = 135
135 bracelets

Answer 1

Well if we look at these equations we can see that D is the only appropriate answer considering 23 + 112 = 135 bracelets.
Yes the equation works as well
b - 23 = 112
we add 23 to both sides
b - 23 + 23 = 112 + 23
b = 135
