Answer:

$680=40m-3$

Step-by-step explanation:

We know that he DOES spend $680, so we can put (680 = )

40 per month would be 40 times how many months total. Since we don't know how many months, we can use (40m)

3 months free simply means that he doesn't have to pay that price so we can take 3 months out of his total (- 3)

Hope this helps!!

The double number line shows the amount of time a hen needs to lay 1 egg.

Scorpion4ik [409]

I realize the double number line in this exercise can be as shown in the attached image, in that case, the table, correctly completed is:

Eggs Time (hours)

3 75

4 100

12 300

Method to complete the table.

First, you must see the double number line (attached image), in this we identify a hen needs 25 hours to lay 1 egg, by this reason, to identify the time required for a certain number of eggs, just multiply the number of eggs by 25 (the number of hours shown on the double number line), then:

3 * 25 = 75
12 * 25 = 300

To calculate the number of eggs taking into account the time, you must divide the hours by 25:

100 / 25 = 4

In this way, you can check that the answers are 75, 4, and 300 respectively, to complete the table in the correct form.
