PLEASE ANSWER ASAP: Danielle's wallet had $2.65 in change:all quarters,dimes and nickels. She had 3 times as many quarters as dimes and one more dime than nickels. How many of each coin did she have?SHOW WORK

Answers

Answer 1
Answer: We can write an equation in terms of n, the amount of nickels:

25(3n+3)+10(n+1)+5n=265.

Thus:

90n+85=265

Subtracting 85, we have:

90n=180

Therefore, n=2.  As such, Danielle has 2 nickels, 3 dimes, and 9 quarters.
Answer 2
Answer: 2.65=3x(25)+x(10)+(x-1)(5)
9 quarters 3 dimes 2 nickels
9*.25+2.25
3*.10=.30
2*.5=10
2.25+.30+.10=2.65

Jamaal buys his clothes at Super Discounts. On Saturday, he bought shoes regularly priced at $40 for 25% off, and a jacket regularly priced at $100 for 30% off. Including a 6% sales tax, what total amount will Jamaal pay? 

Answers

100-25=75%

$40-100%
$ x -75%

100x=3000
x=$30

100-30=70%

$100-100%
$ y - 70%

100y=7000
y=$70

total: x+y=70+30=$100

+ sales tax
100% +6%=106%

$100-100%
$ z - 106%

10600=100z
z=$106

Answer: Jammal will pay $106.

He would pay $30 for the shoes, and $70 for the jacket.

So, in total 106.
