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

1.4

2.3

step-by-step explanation:

the formula for the constant of variation is

y= kx

divide each side by x

y/x =kx/x

y/x =k

we know a and y

1.   y/x = k

4/1 =4

check the other values to make sure they are the same

8/2 = 4   12/3 =4   and 16/4 =4  

the constant of variation is 4

2.   y/x = k

3/1 =3

check the other values to make sure they are the same

6/2 = 3   9/3 =3   and 12/4 =3  

the constant of variation is 3
