Answer:
Step-by-step explanation:
If the triangles are similar, then the sides are in proportion.
We have the equation:
<em>cross multiply</em>
<em>divide both sides by 3</em>
<em>subtract 8 from both sides</em>
<em>divide both sides by 3</em>
We can assume that the y-intercept for this equation is 125, because that would be how much Anna already has saved before she begins saving money from her allowance. Then, we know that Anna adds $2 to her savings each day from the problem, so we know that the slope will be positive 2 then.
Equation:
y = 2x + 125
