You could divide 50 by 5.

If have 8 crayons in all them to gather weigh1,200g how each of them weigh

What. Is a earth model

10

The answer is 10. Every week frank is getting 5 pots. So 50/5 is 10.

To determine the number of pots Mr. Frank received for free, you can set up a simple equation.

Let's assume that Mr. Frank pays for 4 pots of flowers each week and receives one pot for free. The ratio of pots purchased to pots received for free is 4:1.

Now, let's break down the problem:

- In the first week, Mr. Frank buys 4 pots and receives 1 pot for free. So, after the first week, he has a total of 5 pots.
- In the second week, he again buys 4 pots and receives 1 pot for free. So, after the second week, he has a total of 10 pots (5 pots from the previous week + 5 pots from the current week).
- Following the same pattern, after the third week, he will have a total of 15 pots (10 pots from the previous week + 5 pots from the current week).
- Finally, after the fourth week, he will have a total of 20 pots (15 pots from the previous week + 5 pots from the current week).

Since we know that after 4 weeks Mr. Frank has a total of 50 pots, we can now set up the equation:

20 pots (from the fourth week) + x pots (the number of pots received for free) = 50 pots

To solve for x, we subtract 20 from both sides of the equation:

x = 50 - 20
x = 30

Therefore, Mr. Frank received 30 pots for free over the course of 4 weeks.
