lisabon 2012 [21]

Answer: Amount of purchase would be $393.70.

Step-by-step explanation:

One person made a purchase that was financed in three monthly installments and equal to $ 350.00, the financing was made at the compound interest rate of 48% a.a. Determine the amount of the purchase.

Since we have given that

Principal = $350.00

Rate of compounded monthly = 48%

Number of months = 3

So, the amount of purchase would be

$Amount=350(1+\dfrac{0.48}{12})^3\\\\Amount=350(1+0.04)^3\\\\Amount=350(1.04)^3\\\\Amount=\$393.70$

Hence, Amount of purchase would be $393.70.

A 2.2 GB game is being downloaded onto your laptop. When you have downloaded half a gigabyte, you notice that your computer has

andreev551 [17]

Answer:

$0.01m +\frac{1}{2} \geq 2.2$

Step-by-step explanation:

Let m be number of minutes it will take to download the whole game.

We are told that computer is downloading at a rate of 0.01 GB per minute and half GB game is already downloaded. So 0.01*m+0.5 will be equal to 2.2 as game size is 2.2 GB.

Let us find the least number of minutes it will take to download the whole game.

$0.01m +\frac{1}{2} \geq 2.2$

$0.01m +0.5\geq 2.2$

$0.01m \geq 2.2-0.5$

$0.01m \geq 1.7$

$m\geq \frac{1.5}{0.01}$

Therefore, $0.01m +\frac{1}{2} \geq 2.2$ is our desired inequality.
