Answer:
Loss is 250-175=75 rupees
Step-by-step explanation:
Based on the CPI, the expected price is
$12.75 * 193/100 = $24.61
The actual price is $28.50 -24.61 = $3.89 more than expected. The appropriate choice is ...
b. The actual price is $3.89 higher than the expected price.
The answer is A. Acute triangle
Y=3x+5
Gradient=3
y-y1=m(x-x1)
If the points are (7,1)
y-1=3(x-7)
y-1=3x-21
y=3x-20 as your equation
Note: when lines are parallel they have equal gradient
