Questions & Answers
Geneva treated her parents to dinner at their favorite restaurant. The bill was $74.25. Geneva wants to leave 16 % of the total  bill as a tip. How much should the tip be?
74.25 × .16 then get the total and that will be your tip
David
$74.25 x 0.16 = $11.88
total bill:
$74.25 + $11.88 = $86.13
ericka
yes and tip 16% will be $11.88
David
what is the shorter way to do it
Priam has dimes and pennies in a cup holder in his car. The total value of the coins is $4.21. The number of dimes is three less than four times the number of pennies. How many dimes and how many pennies are in the cup?

June needs 48 gallons of punch for a party and has two different coolers to carry it in. The bigger cooler is five times as large as the smaller cooler. How many gallons can each cooler hold?
I hope this is correct,
x=cooler 1
5x=cooler 2
x + 5x = 48
6x=48
×=8 gallons
5×=40 gallons

Avery and Caden have saved $27,000 towards a down payment on a house. They want to keep some of the money in a bank account that pays 2.4% annual interest and the rest in a stock fund that pays 7.2% annual interest. How much should they put into each account so that they earn 6% interest per year?
i did 2.4%7.2% i got 1.2%
Irene
I have 6% of 27000 = 1620
so we need to solve 2.4x +7.2y =1620
Catherine
I think Catherine is on the right track. Solve for x and y.
Scott
next bit : x=(16207.2y)/2.4
y=(16202.4x)/7.2
I think we can then put the expression on the right hand side of the "x=" into the second equation. 2.4x in the second equation can be rewritten as 2.4(rhs of first equation)
I write this out tidy and get back to you...

Darrin is hanging 200 feet of Christmas garland on the three sides of fencing that enclose his rectangular front yard. The length is five feet less than five times the width. Find the length and width of the fencing.
Mario invested $475 in $45 and $25 stock shares. The number of $25 shares was five less than three times the number of $45 shares. How many of each type of share did he buy?
let # of $25 shares be (x) and # of $45 shares be (y)
we start with $25x + $45y=475, right?
we are told the number of $25 shares is 3y5) so plug in this for x.
$25(3y5)+$45y=$475
75y125+45y=475
75y+45y=600
120y=600
y=5
so if #$25 shares is (3y5) plug in y.

will every polynomial have finite number of multiples?
a=# of 10's. b=# of 20's; a+b=54; 10a + 20b=$910; a=54 b; 10(54b) + 20b=$910; 54010b+20b=$910; 540+10b=$910; 10b=910540; 10b=370; b=37; so there are 37 20's and since a+b=54, a+37=54; a=5437=17; a=17, so 17 10's. So lets check. $740+$170=$910.
. A cashier has 54 bills, all of which are $10 or $20 bills. The total value of the money is $910. How many of each type of bill does the cashier have?
whats the coefficient of 17x
