Question

Emma found a 4% interest rate for a $2750 loan for a 3-year term. Blake found the same 4% interest rate on a $2750 loan for a 5-year term. How much more interest will Blake pay on the $2750 loan with the longer term?

this is a growth at a steady rate. This percentage in decimal form is 0.04. Multiply the loan by 0.04 then add the original amount to the product. Do this for each interval.

anonymous · Answer

for example,$$2750*0.04=110$$ 
Now we add 110 to 2750 getting 2860 then you do the same for 2860 and so on. There is an easier way to do this but I am unsure what it is.

so how many times do i do that?

anonymous · Answer

you do it once per interval, so for Blake, 5 times, and Emma 3. After you get the totals, its quite obvious what to do. Find the Difference of the two.
