Best ResponseYou've already chosen the best response.1In the first week there will be 5000 visitors. In the second week, there will be 10% fewer visitors than in the first week. Can you calculate how many visitors there will be in the second week?

Best ResponseYou've already chosen the best response.1No. In math, in addition to solving a problem using some method, you need to look at your answer and see if it makes sense. If there will be 10% FEWER visitors in the second week, how can you end up with 10 times more visitors?

Best ResponseYou've already chosen the best response.1In the first week, there are 5000 visitors. Call the initial number, 5000, 100%. In the second week, there will be 10% fewer visitors. That means in the second week, there will be 100%  10% = 90% of the 5000 visitors.

Best ResponseYou've already chosen the best response.1Now we calculate 90% of 5000. 90% of 5000 = 90/100 * 5000 = 0.90 * 5000 = 4500

Best ResponseYou've already chosen the best response.0so it goes down by 500

Best ResponseYou've already chosen the best response.1You see the table above. That is where we are so far in solving this problem. We know how many visitors there will be in the first and second weeks. Now we need to find the numbers for weeks 3 through 7. Then we add all numbers up.

Best ResponseYou've already chosen the best response.1You asked a good question. The answer is no. The number goes down by 10% of the previous week. Since the first week has 5000 visitors, 10% of 5000 is 500, so from week 1 to week 2 it went down by 500.

Best ResponseYou've already chosen the best response.1Now to find the number for week 3, think of week 2 as 100%. What is 90% of 4500?

Best ResponseYou've already chosen the best response.1You are always losing 10% of the previous week, but each week, the number is decreasing, so 10% of the previous week is going to be less and less each week that goes by.

Best ResponseYou've already chosen the best response.1Exactly. You put it on our table. dw:1439167056423:dw

Best ResponseYou've already chosen the best response.1Now start with 4050, and find 90% of that number. 0.90 * 4050 = 3645 dw:1439167103110:dw

Best ResponseYou've already chosen the best response.1You see how you get the following week's number? Multiply each week's number by 0.9 Fill in the table's right column. Then add all numbers in the right column.

Best ResponseYou've already chosen the best response.1Are you sure the number goes down 10% each week. There is a percent in the problem?

Best ResponseYou've already chosen the best response.1I just reread it. The problem states the number goes down 10 people per week. I read it as 10 percent per week. My mistake. Sorry about that.

Best ResponseYou've already chosen the best response.1That means it's a simpler problem. Let's use the same table, and clear out the second column except for the 5000 in the first week.

Best ResponseYou've already chosen the best response.1Now for each subsequent week, we just subtract 10 from the previous week. As you can see, this is an easier problem than I thought because of my misreading.
