Candlelight Books kept a record of how its sales increased based on

zavuch27 [327]

Answer:

Step-by-step explanation:

We need to understand the meaning of slope. The slope means the rate of change of y with every unit change of x.

In our case, it will be rate of change of sales increase (%) with respect to unit change of discount(%).

The formula for slope is the change in y divided by change in x.

From the 2 points given, we can say that slope is:

$\frac{62-32}{20-10}=\frac{30}{10}=\frac{3}{1}$

This means "as discount increases 1%, sales increase by 3%". Option D is right.

SpaceX launched 94 rockets in 4 years. How many rockets would we expect SpaceX to launch in the next 7 years?

RoseWind [281]

Answer:

164.5, if thats wrong then 258.5

Step-by-step explanation:

Divide 94/4 and then you get 23.5 so you multiply 23.5 x 7=164.5 but I wasn't sure if it was either 4 years and then add another 7 or if it was just 7 years so I also did 23.5 x (7+4)= 23.5x11=258.5
