Answer:
Equation: 1.5s + 20 = 200
How long it will take for Samantha to finish a 200 meter race: 120 seconds
Step-by-step explanation:
The problem says Samantha walks at a rate of 1.5 meters per second. If we let "s" represent seconds, then we can write this as 1.5s. Since she gets a 20 meter head start, you can then write the equation as 1.5s + 20. Finally, its says use this equation to find how long it would take to finish a 200 meter race. So you set the previous equation equal to 200. Or 1.5s + 20 = 200.
To solve for "s" and find how long it would take to finish a 200 meter race, you first subtract 20 from each side. You should be left with 1.5s = 180. Then divide by 1.5. 180/1.5 equals 120. So it will take Samantha 120 seconds to finish the 200 meter race.
Since it's 8% every year, we have 8% of 600 equals 8*6=48. 48/365 is the amount of interest per day, and 48*45/365 is what you would get over 45 days, which is approximately 5.9 dollars
Note that this is assuming interest is compounded every year
