I got the answer because I detected a pattern. Did you notice that to go from 16 to 48, you add 32. From 48 to 80, you add 32. Now, as we know the pattern, we add another 32. So, 80 plus 32 would be 112. That is your answer, and that is how I got it. I hope you understand! Comment if this is brainy enough to be okay to understand!

You bike
Lyrx [107]
<h2>Answer:</h2>

<em>You will bike 30.2 miles in the seventh day according to the prediction.</em>

<h2>Explanation:</h2>

Here we have the following data, You bike

  • 5  miles the first day of your​ training,
  • 5.4 miles the second​ day,
  • 6.2 miles the third​ day, and
  • 7.8 miles the fourth day.

So we can know some facts:

  • From the first day to the second day the number of miles increases:

5.4-5=0.4mi

  • From the second day to the third day the number of miles increases:

6.2-5.4=0.8mi

  • From the third day to the fourth day the number of miles increases:

7.8-6.2=1.6mi

By taking a look at the pattern, we can see that each day you increases the number of miles by a factor of 2 compared to the previous day. So:

  • From the fourth day to the fifth day the number of miles increases:

x_{5}-7.8=3.2mi \\ \\ x_{5}=7.8+3.2=11mi, \ \text{Day 5}

  • From the fifth day to the sixth day the number of miles increases:

x_{6}-11=6.4mi \\ \\ x_{6}=6.4+11=17.4mi, \ \text{Day 6}

Finally:

  • From the sixth day to the seventh day the number of miles increases:

x_{7}-17.4=12.8mi \\ \\ x_{7}=12.8+17.4=30.2mi, \ \text{Day 7}

So, in this problem you already have the equations set up for how much money each one works. You have Jim, earning a starting amount of $35, plus an additional $3 for every hour he works. You also have John, who gets $8.


The variable in the equations is h, which stands for hours. From there, you can put the three different h values (6, 7, and 8) into the equations to see who gets more money.


For instance, for Day 1, Jim gets 35+3x6 dollars, or 35+18=$53, while John gets 8x6 dollars, or $48. You can substitute in 7 and 8 and do the same process to get the answers for Day 1 and 2.


Hope this helps!
