40*7.20= 288
Then
You have 15 hours at 1.5*7.20= 10.80
15*10.80= 162
162+288= 450. Sasha made $450
If the interest is simple interest, then the value is
100 [ 1 + (10 x 0.11) ] = 100 (1 + 1.1) = 100 x 2.1 = $210 .
If the interest is compound interest, and is compounded annually,
then the value is
100 (1 + 0.11)¹⁰ = 100 (2.8394) = $283.94 .
If the interest is compound interest, and is compounded monthly,
then the value is
100 (1 + 0.11/12)¹²⁰ = 100 (2.9891) = $298.91 .
That's why compound interest is better than simple interest.
Combine like terms (4x+6)(2x-5)
foil 8x^2-20x+8x+1
set equal to zero and use quadratic formula
x=23/16 and x=1/16
2x^3 but i could be wrong i had to do it in my head
