Please help solve. Lydia started collecting seashells when she was five years old. At age seven, Lydia had 12(10) ? seashells. At age nine,
Lydia had 24(10) ? seashells. At age eleven, Lydia had
48(10)? seashells. Lydia wants to collect 75(10) 3 seashells.
Lydia continues to collect seashells at the same rate.
How old will Lydia be when she has 75(10): seashells?
Show all your mathematical thinking. Lydia will be 13 when
she has 75(10)

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

really your just stupid if you don't know this
