Annual rate = 1.05%

Simple interest formula is I = Prt * 100
Where P is principle, I is interest, r is rate and t is time.

Transpose to make r the subject

Prt * 100 = I
r = I/ Pt * 100

Substitute values into the equation.
Let I = $1260, P = $30,000 and t = 4 years

r = $1260/ $30,000 * 4 * 100
r = 0.0105 * 100
r = 1.05%

7 . Cans of frozen OJ Total Cost ($) 1.25 1 2 2.50 3 3.75 4 5.00

aliina [53]

$\begin{gathered} x=\text{cans of frozen OJ} \\ f(x)=\text{Total cost(\$)} \\ f(x)=1.25x \\ f(1)=1.25(1)=1.25 \\ f(2)=1.25(2)=2.50 \\ f(3)=1.25(3)=3.75 \\ f(4)=1.25(4)=5.00 \end{gathered}$

Independent variable = x(Cans of frozen OJ)

dependent variable = y(total cost)
