Question

Teddy is preparing to sell some wooden blocks at a garage sale. Before pricing individual bags of blocks, he decides to determine the approximate number of blocks per pound by researching the weights of different sets of blocks. The graph shows his data. A graph shows weight of set (pounds) labeled 0.5 to 5 on the horizontal axis and number of blocks on the vertical axis. A line increases from 0 to 5.5. About how many blocks are there per pound? Round to the nearest block. 10 20 30 40

Answer 1

The correct option is B) 20.

Step-by-step explanation:

Consider the provided information.

The graph is shown below:

We have to find the number of blocks per pounds.

In order to find the number of blocks per pound we first find two points through which line passes.

From the graph the Points are (2.5,50) and (5,100).

Now find the Slope of line that will gives us the number of blocks per pounds.

$\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}$

Substitute $\left(x_1,\:y_1\right)=\left(2.5,\:50\right),\:\left(x_2,\:y_2\right)=\left(5,\:100\right)$

$m=\frac{100-50}{5-2.5}=20$

Thus, there are 20 blocks per pounds.

The correct option is B) 20.
