Answer:

5% represents the rate of interest per annum.

Step-by-step explanation:

It is given Loretta invested $1000 in simple interest account yeilding 5% paid annually and amount in her account after 2 years is $1100 that is she earned 1100-1000=$100 interest in 2 years.

Simple interest can be calulated by the formula S.I=P T R

P represntes the principal ,T = time ,R= rate of interest .

P=$1000,T= 2 years ,R= 5%=0.05.

S.I = 1000(2)(0.05)

S.I= 100

Interest earned is $100 on an investement of $1000 for 2 years at the rate of interest of 5% annually.

Suppose you are the manager of a firm. The accounting department has provided cost​ estimates, and the sales department sales​ e
Katarina [22]

Answer:

<em>If more than 134 articles are produced and sold, the firm will have positive profits and shoule start production</em>

Step-by-step explanation:

Cost, Revenue, and Profit Function

The cost function C(x) is given by

C(x)=75x+3,350

where x is the number of produced products.

The revenue function is

R(x)=100x

With both equations, we can know the profit function as

P(x)=R(x)-C(x)

P(x)=100x-75x-3,350=25x-3,350

P(x)=25x-3,350

For the firm to have positive profits, it has to produce x articles with the condition

P(x)>0

Or, equivalently

P(x)=25x-3,350>0

Solving for x

\displaystyle x>\frac{3,350}{25}

Thus

x>134

This means that if more than 134 articles are produced and sold, the firm will have positive profits and shoule start production

How much should you invest now at 7 1/4% simple annual interest in order to earn $190 interest in 4 months?
vlabodo [156]

Answer:

so principal amount is $7862.07

Step-by-step explanation:

Given data

rate = 7*1/4 % = 29/4 %

interest = $190

time = 4 months = 4/12 year

to find out

principal

solution

we know the simple interest formula  i.e.

interest = ( principal × rate  × time ) /100             ..................1

now put all value rate time and interest in equation 1 we get interest here

interest = ( principal × rate  × time ) /100  

190 =  ( principal × 29/4  × 4/12 ) /100  

principal = 190 × 12  ×100 /   29

principal = 7862.068966

so principal amount is $7862.07
