Janelle has 342 pennies, 62 nickels and 12 dimes
if she exchanges her coins for dollars, how many dollars and cents will she have?

Step-by-step explanation:

There’s 100 cents in a dollar. 342 pennies, at one cent each, adds up to $3.42. A nickel is 5 cents each. .05 x 62 =3.1. This is $3.10. A dime is 10 cents each. .10 x 12 = 1.2. This is $1.20. Add all of them up. 3.42+3.10+1.20=$7.72. She will have 7 dollars and 72 cents left. I hope this helps!

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)
