Julie invested 3000 in a simple interest account for 2 years. At the end of the 2 years, she had earned $75 in interest. What wa

Dahasolnce [82]

The simple interest rate was: 1.25%

Step-by-step explanation:

Simple interest is given by:

$A = Prt\\Here\\A => Interest\\P=>Principal\ Amount\\r => Rate\\t => Time\ in\ years$

Given

Principal amount =$3000

Time = t = 2 years

Interest amount = A = $75

putting the values in the formula

$75 = 3000 * r * 2\\75 = 6000r$

Dividing both sides by 6000

$\frac{6000r}{6000} = \frac{75}{6000}\\r = 0.0125\\$

So,

The rate is:

0.0125 * 100 = 1.25%

Hence,

the simple interest rate was: 1.25%

A babysitter charges a rate of $15 per hour. how long was the babysitter there if she makes $5

Anika [276]

Answer:

20 mins.

Step-by-step explanation:

A babysitter charges a rate of $15 per hour. How long was the babysitter there if she makes $5?

x = hours she babysat

Equation:

15x = 5

Divide to isolate x:

15x = 5

/15 /15

x = 1/3 hrs.

Now, we convert into minutes, since she didn't work for a whole hour, to earn the $15

We know that there are 60 mins. in an hour

60 * 1/3

60/3

20 mins.

Therefore, the babysitter was there for 20 mins.

Hope this helps!
