During your first week of training for a marathon, you run 10 total miles.you increase the distance you run by 20% each week.how many miles do you run during your 12th week of training?

Multiply 20% by ten to get 2. This will be the number of miles increased each week. Multiply 2 by 12 to get the total number of miles ran since the start of the increase. Add 10 miles and you will get 34 as your final answer.

Joseph pays: $ 133.2

Step-by-step explanation:

Let's go through the problem. Joseph wants to buy a television that currently costs 40 percent off of it's original price of 740 dollars. First convert 40% to a decimal form. Moving the decimal two points right you would receive 0.4. Using this let's calculate the cost off of the television:

0.4 * 740 = 296 dollars

Now as this is the cost off of the television, to calculate the current cost of the television, let's simply subtract the cost off of the television from the original cost of the television:

740 - 296 = 444 dollars

Let's further read the problem. Joseph's dad agrees to buy the television if Joseph pays 30 percent of it's current cost. Here we can use a similar process as before. Convert 30% to a decimal form. Moving the decimal two points right you would receive 0.3. Using this let's calculate the cost Joseph has to pay for the television:

0.3 * 444 = 133.2 dollars
