Can someone see if I did this right I got 8937.5
garik1379 [7]
It will be $8937.5 because you have to multiply 6500 by .075 (that’s the percent as a decimal) and then multiply the product by 5 years, which will equal to 2437.5. Next you add the interest, which is the total, by the principle, 6500, and you will get the balance of $8537.50. So yes you are correct

Which is larger 1 meter or 105 centimeters?
amm1812
"centi" means "hundredth". Think "cent" as in "penny". There are 100 cents or 100 pennies in a dollar.

That helps me remember that 
1 meter = 100 centimeters

The original "1 meter or 105 centimeters" turns into "100 centimeters or 105 centimeters"

At this point, it is clear that 105 is larger than 100. So 105 cm is larger than 1 meter.
