So you know that 1 cubic foot is equal to 80 pounds. So, the first point would be (1,80).
You can find the other points by multiply 80 by a number, and when I did that, I got (2,160) and (3,240) too.

I hope this helps :)

natali 33 [55]

Answer:

Step-by-step explanation:

Assuming that each section is rectangular, each area can be found with

$A= w \times l$

Where $w$ is width and $l$ is length.

Notice that the area of each section is found with the product of width and length, that means the right answer must be a product.

Therefore, the right answer is the second choice.

1. A family eats at a restaurant. The bill is $42. They have a coupon that gives them 15% off

Ludmilka [50]

<h2>a.</h2><h3>Solution:</h3>

$42 - 42 \times 15\%$

$=42 - 42 \times \frac{15}{100}$

$=42 - 21 \times \frac{15}{50}$

$=42 - \frac{315}{50}$

$= 42 - 6 \: \frac{15}{50}$

$= 41 \: \frac{50}{50} - 6 \: \frac{15}{50}$

$= 35 \: \frac{35}{50}$

$= 35.70$

<h3>Answer:</h3>

The family did spend $35.70 on the meal after the coupon

<h2>b.</h2><h3>Solution:</h3>

$35.70 + 42 \times 20\%$

$= 35.70 + 42 \times 0.2$

$= 35.70 + 8.4$

$= 44.10$

<h3>Answer:</h3>

The family did spend $44.10 on the meal in total.
