Question

groovy gears sells robotics kits of different sizes. this scatter plot shows the price of each kit and the number of pieces it includes. robotics kits how many more pieces are in the $100 kit than in the $20 kit? more pieces

Explanation:

Step1: Find the number of pieces for each kit

From the scatter - plot, for the $x = 20$ (price), the $y$-value (number of pieces) is $y_1=10$. For the $x = 100$ (price), the $y$-value (number of pieces) is $y_2 = 80$.

Step2: Calculate the difference

The difference in the number of pieces is $y_2-y_1$. Using the formula $y_2 - y_1$, we substitute $y_1 = 10$ and $y_2=80$. So, $80 - 10$.

Answer:

$70$
