Hello,
1) Finding the slope of the line passing throught the 2 points:
m=(-8-6)/(7-2)=-14/5.
A perpendicular line has a slope of -1/m=5/14
So the line searched has for equation:
y+1=(x-2)*5/14
or 10x-28y+73=0
4 sticks and 2 brushes
(10.5*4)*(24*2)=90
Answer:
$22.33
Step-by-step explanation:
A 20% tip would be 0.20. Multiply the cost by 0.20 to get the tip amount or multiply the cost by 1.20 to get the total amount including tip.
subtotal --> $18.61
tip --> $3.72
18.61 x 0.20 = 3.72
total --> $22.33
There's no question provided, however, from a business-minded perspective, this is a very wise investment that he is making. This is because he has both short and long-term plans covered for himself in any case that certain situations would arise.
