1- The answer is that she wants the new time to be 32 minutes

Solution: The question asks that she wants to DECREASE by 20%

What you will do it convert 20% to a decimal (which is 0.20)

Then, you need to multiply the minutes by the decimal:

40 x 0.20 = 8 minutes

Now you know that 8 minutes will be 20% of 40 minutes, so you just subtract 8 from 40 UwU

Marshall invest $4500 into an account bearing 6% interest compounded semiannually. How much interest will be added into this acc
Sphinxa [80]

Answer:

$1547.62

Step-by-step explanation:

The principal Marshall invested is $4500.

The rate of interest is 6%

The compound interest formula is

A=P(1+r)^n

We substitute P=4500,r=0.06 and t=5 to obtain:

A=4500(1+ \frac{0.06}{2} )^ {2 \times 5}

We simplify to get:

A=4500(1+ 0.03)^ {10} = 4500 \times  {1.03}^{10}

This gives us:

A=6047.62

The interest after 5 years is

6047.62 - 4500 = 1547.62
