Original price = $600
Profit= $900-$600=$300
<u>d)Calender's</u>
%Profit=25%
Selling price=$3120
This means;
125%=$3120

Using a linear regression calculator. The best fit line obtained is :
ŷ = -1.618X + 215.636 ; which shows decrease in weight has the number of weeks grow.
Carters weight 15 Weeks into his diet :
X = 15
ŷ = -1.618(15) + 215.636
= 191.366
= 191 (nearest whole number)
