Answer:
- 7 quarters, 14 dimes, 7 nickels total $3.50
- $0.80 will remain
Step-by-step explanation:
a) 1/4 of 28 = 28/4 = 7 coins are quarters.
2/3 of (28 -7) = (2/3)(21) = 14 coins are dimes
The remaining 28 -7 -14 = 7 coins are nickels
__
b) The amount of money in coins is ...
7×$0.25 +14×$0.10 +7×$0.05 = $3.50 . . . in coins
__
c) 2 packs of cards at $1.35 each will cost 2×$1.35 = $2.70. After the purchase, the remaining money would be ...
$3.50 -2.70 = $0.80 . . . remaining
2p - 3q - 4r + 6r - 2q + p = 0
2p + p - 3q - 2q - 4r + 6r = 0
3q - 5q + 2r = 0
A useful formula for finding the effective rate on discounted notes is
.. (effective rate) = r/(1 -rt)
For t=(3 months)/(12 months) = 1/4, the effective rate on these bills is
.. (effective rate) = 3.75%/(1 -0.03750*0.25) ≈ 3.79%
There was a gross income of 34,100....8% goes to 401K plan..
8% of 34,100 = 0.08(34,100) = 2728
he gets paid bimonthly...so he gets paid twice a month...and being that there is 12 months in a year, he gets paid (12 * 2) = 24 times
2728/24 = 113.666 rounds to 113.67 each paycheck <==
