Answer:
y = 2/7 x - 51/7
Step-by-step explanation:
Equation of the line
(y-y1)/(y2-y1) = (x-x1)/(x2-x1)
(y-(-7)/(-9-(-7) = (x-1)/(-6-1)
(y+7)/-2 = (x-1)/-7
(-y-7)/2 = (-x+1)/7
-y-7 = -2/7 x + 2/7
-y = -2/7x +2/7 + 7
y = 2/7 x - 2/7 - 7
y = 2/7 x + (-2-49)/7
$152.33
123.85 x 0.05 = $6.19
123.85 x 0.18 = $22.29
123.85 + 6.19 + 22.29 = $152.33
Cost of 12 pencils = 37 4/5 = 189/5
Cost of 1 pencil = 189/5 ÷ 12
= 189/5 x 1/12 = 189/60 = 63/20 = 3 3/20
So required answer is 3 3/20
