Problem page the price of a notebook has dropped to $3.20 today. Yesterday's price was $3.45 . Find the percentage decrease. Rou

Anna11 [10]

Yesterday's price of notebook = $3.45

Today's price of notebook = $3.20

We have to determine the percentage decrease in the cost of notebook.

Percentage decrease = (Decrease $\div$ Old price) $\times 100$

So, percentage decrease = $\frac{3.45-3.20}{3.45} \times 100$

= $\frac{0.25}{3.45} \times 100$

= 7.246%

= 7.25%

Therefore, there is 7.25% of decrease in the cost of the notebook.

Find the slope of the line through the given points

coldgirl [10]

I can’t solve all of them but maybe one and I will give you the formula for you to solve the rest.
Slope = (y2 -y1) / (x2 -x1).
m= ( 16 -(-3)) / ( -14 -(-9))
m = (16+3)/(-14+9)
m = 19/ -5
