Manuela wants to have $26,000 in 18 months. about how much should she put into an 18 month cd that earns simple interest of 5.6% a year calculated semiannually in order to reach her goal.

Manuela should put $23,985.24 into an 18 month CD.

Step-by-step explanation:

Manuela wants to have $26,000 in 18 months CD that earns simple interest of 5.6% a year calculated semiannually.

Since it is simple interest so in 18 months (1.5 years)  it will earn = 5.6 × 1.5 = 8.4%.

Formula for Simple interest

A = P( 1 + rt)

A = amount ( 26,000 )

P = Principal  ( we have to find out )

r = Rate of interest in decimal 8.4% ( 0.084 )

t = time ( 1 )

Let the principal amount be x

Now we put the values in formula to find the value of x.

26,000 = x ( 1 + 0.084 × 1 )

26,000 = x ( 1.084 )

x =

x = 23,985.23985 rounded to 23,985.24

Manuela should put $23,985.24 into an 18 month CD.

725 parts per hour.

step-by-step explanation:

hi there, this answer is actually really simple.

you can set it up as 1450/2 or 3625/5 to find the answer.

they want to know how much per hour is being made, so you just divide.

1450/2=725.

and that's how many are produced per hour.

hope this . : )

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )
