now, we're assuming she made the deposit at the child's birth, namely when year was 0, at the child's twenty-first birthday that'll be 21 years later.
Answer:
A = 20% B = 36%
Step-by-step explanation:
35 in total bought
2/10 = who bought model A = 20%
16+9 = 25 => 9/25 who bought model B = 36%
Equation = y = mx + b
y = 3/4x + b
Calculation for b.,
-5 = 3/4 * 4 + b
b = -5/3
So, your final answer is y = 3/4x - 5/3
Hope this helps!

y = -x + 1
