Answer:
52$
Step-by-step explanation:
ok so 2 pins cost 4$ so if you buy one pin its 2$ correct? take 12 and multiply it by 2 and take 14 and multiply by 2,
12×2=24$
14×2=28$
add those two together and you get 52$
Plugging in the data points into a quadratic regression application, we get the following regression:
y = ax^2 + bx + c,
where:
a= 0.00267857
b= 0.0110714
c= 2.85743
with an R² value of 0.9851
