An amount of $1000 was deposited in a bank at a rate of 6% compounded quarterly for 5 years. the rate then increased to 10% and was compounded quarterly for the next 5 years. if no money was withdrawn, what was the balance at the end of this time?

FV= $2,206.979

Step-by-step explanation:

Step 1: Find FV at the end of first 5 years at 6% rate;

FV=PV(1+r)^t

since it's quarterly-compounded, r/4=6%/4 = 1.5% and t=5*4= 20 periods

FV= 1000 * (1.015)²⁰

FV=1000* 1.346855

FV=$1,346.855

Step 2: Find FV of $1346.855 for the next 5 years at 10% rate;

FV=PV(1+r)^t

since it's quarterly-compounded, r/4=10%/4 = 2.5% and t=5*4= 20 periods

FV= 1346.855 * (1.025)²⁰

FV=1346.855* 1.638616

FV=$2,206.979

answer: 180

step-by-step explanation:

12-2=10

20-2=18

18x10=180
