Answer:
The principal amont was $35,000
Step-by-step explanation:
This is a simple interest problem.
The simple interest formula is given by:
In which E are the earnings, P is the principal(the initial amount of money), I is the interest rate(yearly, as a decimal) and t is the time.
In this problem, we have that:
We want to find P. So
The principal amont was $35,000
Answer:
Step-by-step explanation:
It is vital to first find the gradient/ slope between the points
let us use the point (6,1) to find the value of c
y=mx+c
1=1(6)+c
1-6=c
∴c=-5
the equation is given by
y=x-5
Let h be the numbers of hours, f be the one-time fee and c the cost charged. The equation is
Since you pay $15 per four, plus the fee. We can solve this equation for the fee:
If we plug c=195 and h=9, we have
