Answer:
Ex1: If $1000 is invested now with simple interest of 8% per year. Find the new amount after two years. P = $1000, t = 2 years, r = 0.08.

hope this helps
Divide the numerator by denominator: 1/6=.1667; 4/25=.16. Change to percents by moving decimal: Ankara: 16.6% or 17%; Juanita: 16%. Find the time difference: 16:00-13.30=2:30. Divide by 100: 2.5/100=.025. Change to percent: Julia: 2.5% or 3%. Tisha reduced her time the most :)

Answer:
11
Step-by-step explanation:
The two equations appear to be ...
- 12x +4y = 152
- 32x +12y = 420
These can be solved for y using Cramer's rule:
y = (152(32) -420(12))/(4(32) -12(12)) = -176/-16 = 11
The cost of the vegetarian lunch is 11.

<em>Comment on Cramer's Rule</em>
For equations ...
ax +by =c
dx +ey = f
The solutions are ...
x = (bf -ey)/(bd -ea)
y = (cd -fa)/(bd -ea) . . . . note the denominators are the same expression
Once you memorize the pattern of products, this can be the simplest way to solve a pair of equations--especially if you only need one of the variable values.
The cost that he will raise is $23
it's how I get the answer 20+20*15%=20+3
