Every day you collect 4 pennies and keep them in a jar. So the first day

Every day you collect 4 pennies and keep them in a jar. So the first day you have 4 pennies, the (I point ) second day you have 8 pennies, the third day you have 12 pennies, etc. How many do you have on the 15 th day?

Expert Solution

On the first day, you have 4 pennies.

On the second day, you collect 4 more pennies, so you have a total of 4 + 4 = 8 pennies.

On the third day, you collect 4 more pennies, so you have a total of 8 + 4 = 12 pennies.

You can see that the number of pennies you have on each day is increasing by 4 each time. So, on the 15th day, you will have:

4 + (15 - 1) x 4 = 4 + 56 = 60 pennies.

Therefore, on the 15th day, you will have 60 pennies in the jar.
