, whereas the outer hexagon meets the axis at 
So, we're looking for a dilation constant
such that

So, solving by k we have

Answer:
30 years old
Step-by-step explanation:
Let the two ages be A and C.
Then C = (1/2)A, and A = C + 15.
Substitute C + 15 for A in C = (1/2)A:
C = (1/2)(C + 15), or 2C = C + 15.
Then C = 15, and A = C + 15 becomes A = 15 + 15, or A = 30.
Answer:
98 : 15 = 6 R 8
She can pay for six months 6*15 = $90 and she will have $8 left.
