Jane's friend is wrong, the original price would be $200
Answer:
The answer is
<h2>15x - y = - 126</h2>
Step-by-step explanation:
To find the equation of the line we must first find the slope (m)
So the slope of the line using points
(-8,6) (-9,-9) is
So the equation of the line using point (-8,6) and slope 15 is
y - 6 = 15( x + 8)
y - 6 = 15x + 120
Writing the equation in the form
Ax+By=C
We have
15x - y = -120-6
The final answer is
<h3>15x - y = - 126</h3>

Answer:
(a) 2.27 lb/$
(b) 0.10 mi/min
Step-by-step explanation:
<h3>(a)</h3>
Pounds per dollar is found by dividing pounds by dollars:
(25 lb)/($11.00) ≈ 2.272727... lb/dollar
The digit in the thousandths place is less than 5, so that digit and all digits to its right are dropped when rounding to hundredths.
2.27 pounds per dollar
__
<h3>(b)</h3>
Speed in miles per minute is found by dividing miles by minutes:
(6 mi)/(58 min) ≈ 0.103448... mi/min
Rounding to hundredths is done the same way as above.
0.10 miles per minute
_____
If the digit to the right of the place you're rounding to is 5 or more, then 1 is added in the place you're rounding to when digits to its right are dropped.
