Principal, $5000; Annual interest rate, 5.2%; time, 3 years
How much balance after 3 years

5780

Explanation:

Using the formula i = prt we first solve for the amount of interest accumulated over the 3 year time period.

So now we know that we accumulated $780.00 worth of interest  over the 3 year time period. Now, in order to find out how much is in the account we ad the amount of interest to the principle. Or, solve i + p = b

So, the balance will be 5780 after 3 years.

its adding 5.5 each time

step-by-step explanation:

if gloria has "carry over" minutes, (that is, any minutes paid for but not used in a month can be applied to her payment for minutes in the next month,) her total usage for the three months is: total minutes = 320 + 243 + 489 = 1052 minutes number of 200 minute blocks = 1052/200 = 5 r52 (that is 5 with a remainder of 52) rounding up the number of 200 minute blocks gives her usage for the three months as 6 blocks. the cost for six blocks is 6 x $25 = $150 she also has 200 - 52 or 148 carry over minutes if gloria pays each month and unused minutes are lost, applying the rounding up procedure to each month gives: first month usage of 320 minutes rounds up to 2 blocks of 200 minutes for a payment of 2 x $25 = $50 second month usage of 243 minutes rounds up to 2 blocks of 200 minutes for a payment of 2 x $25 = $50 third month usage of 489 minutes rounds up to 3 blocks of 200 minutes for a payment of 3 x $25 = $75 total payments for the three months are $50 + $50 + $75 = $175 get the plan with carry over minutes!
