22.95-8.95=14. Fourteen, is the total amount for your 8 pairs of socks. So now you take the 14 and divide it by 8 to find out how much EACH pair costs. Answer: $1.75 each pair of socks.
First thing the formula is slightly mistated.
it should be
A=P(1+r/n)nt (you had rt fo the exponent and it should be nt
now lets solve this thing
you want A = 2P (double your money
2P = P(1+r/n)nt
we can divide through by P adn put in the values we know
2 = (1+.085/2)2t
2 = (1.0425)2t
and now we can take the log of both sides to make it easy to solve our equation
log(2) = 2tlog(1.0425)
.301 = 2t (.018)
divide both sides by .018
16.653 = 2t
t = 8.327 (number of years to double your money at this rate
check it
(1.0425)16.653 =2
Answer:
x=2 or x=8
Explanation:
Step 1: Write the equation in the correct form. In this case, we need to set the equation equal to zero with the terms written in descending order.
Step 2: Use a factoring strategies to factor the problem.
Step 3: Use the Zero Product Property and set each factor containing a variable equal to zero.
Step 4: Solve each factor that was set equal to zero by getting the x on one side and the answer on the other side.
x2+16=10x
Step 1: Subtract 10x from both sides.
x2+16−10x=10x−10x
x2−10x+16=0
Step 2: Factor left side of equation.
(x−2)(x−8)=0
Step 3: Set factors equal to 0.
x−2=0 or x−8=0
x=2 or x=8
