Three years ago clara bald money from her father to pay for a class trip she agreed to pay 6% simple annual interest on the loan now she owes him $90 in interest plus the principal amount how much did claire borrow

$76.27

Step-by-step explanation:

Consider the equation for simple interest:

I = P x R x T

I is the interest, P is the principal amount, R is the interest rate, and T is the time in years.

If we had to use the equation using the info given, we will see that I(interest) will be equal to the total amount she owed minused by the principal. (I=A-P)

Therefore, substituting the numbers in, we will get an equation like this

90 - P = P x 6% x 3

P = 90 - 0.18P

P + 0.18P = 90

P = 76.27 ( corrected to 2 d.p.)

Since P principal is also the amount of money she borrowed, the answer is $76.27.

step-by-step explanation:

given the function as;

write the equation replacing f(x) with y

form   and fill a table containing values of y with corresponding values of x

you can take a range for   values of x as -3≤x≤3

solving for x=-3

for x=-2

repeat the same procedure to get the values of y for the remaining ,x=-1 to x=3

plot the values of y against values   of x and obtain the following graph
