Week       Balance
1                  $10

6                  $80

using the infomation from the table, write an equation that represents the balance in jeffrey's bank account as a function of the number of weeks

i forgot how to find the equation

visoth · Answer

14x-4 i don't remember the exact way either but for this problem i made x the number of week and y the balance and then i look to see what the difference in balance was weekly, and it turn out ot be 14

i made that my coefficient (14x) and then i plug in the first week which was 1 obciously 14(1) which gave me 1 obviously that doesnt correspond to the balance that is suppose to be 10 so i subtract 4 to give me ten, s my new equation was 14x-4 plug in the other numbers to check and voila
