0.05 + 0.1y = 0.12 - 0.06y

Step-by-step explanation:

Given

(A)

Initial = 0.05

Rate = 0.1

(B)

Initial = 0.12

Rate = -0.06 -- it is negative, because it decreases

Required

When both will be equal

The current amount is calculated using:

Amount = Initial + Rate * y

Where:

$y \to years$

For A, we have:

Amount = 0.05 + 0.1 * y

Amount = 0.05 + 0.1y

For B, we have:

Amount = 0.12 - 0.06*y

Amount = 0.12 - 0.06y

Both are equal when:

0.05 + 0.1y = 0.12 - 0.06y
