This is an arithmetic series with first term a1 = 3 and common difference = 3
Sum after 365 days = (365/2)[ 2*3 + (365-1)*3]
= 200,385 pennies = $2003.85 Answer
Find 10% of $19,200 = 1,920
Find 2% of $1,920 = 384
12% = $2,304
19,200 - 2,304 = 16,896 (year 1)
Repeat this until you have your 5th year :)
She spent $23.25, how I got my answer.
I divided $13.50÷2=$6.75 then I added $6.75+3=$9.75 then I added $9.75+$13.50=$23.25.
I hope this helps.
Start by making the denominators equal.
1/3 becomes 4/12
1/6 becomes 2/12
and you have 5/12.
Add together to get 10/12.
Once simplified, the answer should be 5/6.
Twice the difference of a number and 3 is at most 27
2*(n-3) <=27
to solve
distribute
2n -6 <=27
add 6 to each side
2n <=33
divide by 2
n <=33/2
n<= 16 1/2
