A phone company is offering several different prepaid data plans.

yulyashka [42]

The data plan that has the cheapest deal is given by the ratio of the data

plan price to the GB allocated.

The deal that has the cheapest price per GB is B. Prepaid Single Phone Plan $45 for 16 GB.

The given phone data plans are;

$\begin{tabular}{|l|cl|}&Prepaid Single Phone Plan&Prepaid Family Plan\\ a&\$30 for 1 GB &\$30 for 1 GB\\b& \$35 for 6 GB & \$40 for 6 GB\\ c&\$45 for 16 GB&\$50 for 16 GB\\d & \$65 for Unlimited Data & \$70 for Unlimited Data\end{array}\right]$

The price per GB are;

Plan a = $30 ÷ 1 = $30 per GB

Plan b = $35 ÷ 6 = $5.8 $\overline 3$ per GB and $40÷ 6 = $6. $\overline 6$ per GB for Family Plan

Plan c = 45 ÷ 16 = $2.8125 per GB and $3.125 per GB

Plan d = $65 for Unlimited Data = 65 ÷ ∞ ≈ 0; $70 for Unlimited Data = 0

Therefore, the plan with the cheapest price per GB from the given option is option B. Prepaid Single Phone Plan $45 for 16 GB.

Please help <3!!!!!!!!!

GREYUIT [131]

Answer:

Step-by-step explanation:

the picture is extremely diffuse and out of focus.

but I think I understood the content.

first the easiest part : the straight line on the right side of the graph.

we see the y increases exactly like the x. so, x increases by 2, then y increases by 2 too.

therefore the slope is 1 (y change / x change), and the function is simply y = x

and the line only starts with x=2 and goes on for all x greater than 2.

just for that alone it can be only D, because all the other answer options violate that behavior.

and the left part of the function must confirms this.

first of all, it has to be for x < 2 (again, only D).

and I found |-x²| really funny. this is the same as simply x², as a squared number can only be positive. so, making it negative and then taking the absolute value of that result creates the same original positive number again.

and x² can't be the function, because that would be a parabola that starts at the origin (0, 0), and then curves up left and right from there.

so, this can't be our function in the graph.

again, D is the the only fitting answer.

Your family plans to start a small business in your neighborhood. Your father borrows $10,000 from the bank at an annual interes

valkas [14]

Answer:

$2400

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 8%/100 = 0.08 per year,

putting time into years for simplicity,

36 months ÷ 12 months/year = 3 years,

then, solving our equation

I = 10000 × 0.08 × 3 = 2400

I = $ 2,400.00

The simple interest accumulated

on a principal of $ 10,000.00

at a rate of 8% per year

for 3 years (36 months) is $ 2,400.00.
