Find the principal which amounts to $918 in 1 year at a simple interest<br> of 2% per annum
Fantom [35]

Answer:

P = $900

Step-by-step explanation:

Simple Interest Formula: A = P(1+rt)

Where A is the final amount,

P = Principal

r = Interest Rate in Percent or \frac{r}{100} per annum

t = time in years

From the information given in the question,

A = $918

r = 2% per annum or \frac{2}{100}

t = 1 year

Lets substitute these values to find P, the principal.

P(1+(\frac{2}{100} )(1))=918\\P(1+0.02)=918\\1.02P=918\\P = \frac{918}{1.02} \\=$900

Therefore, P = $900

This problem I can’t seem to figure out
allochka39001 [22]

Answer:

39 touchdowns and 13 fieldgoals

Step-by-step explanation:

Let t= touchdowns

f = fieldgoals

They scored 35 times

t+f = 35

Touchdown is 7 pts and fieldgoal is 3 pt

7t+3f = 193

Multiply the first equation by-7

-7t -7f =-245

Add this to the second equation

-7t -7f =-245

7t+3f = 193

----------------------

   -4f =-52

Divide by -4

-4f/-4 = -52/-4

f = 13

Now we can find t

t+f = 35

t+13 = 52

Subtract 13 from each side

t+13-13 =52-13

t =39
