Kellie has a savings account balance of $2,219 and withdraws $84.75 each month to pay her utilities bill. Edgar has a savings account balance of $1,544 and withdraws $39.75 each month for his credit card payment. Write and solve an equation to determine how much time in months (t) it will take for the two savings accounts to have the same balance.

b. 6

step-by-step explanation:

we are given the table representing an exponential function.

we can see from the table that, as x is increasing, the value of y is increasing in the power of 6.

i.e. the following relation is obtained,

x = 1, y = 6

x = 2, y = 36 =

x = 3, y = 216 =

x = 4, y = 1296 =

x = 5, y = 7776 =

so, the geometric series obtained is .

thus, the common ratio is given by = = 6.

hence, the common ratio is 6.

6 times 7 = 42
