Every year, the price of the smartphone is the 67\% of the price of the previous year (since we lose the 33\%, we remain with the 67\%).


Since 67\% can be written as \frac{67}{100}, the price after one year will be


243 \cdot \frac{67}{100} = 162.81


After two years, the price is the 67\% of the price after one year:


162.81 \cdot \frac{67}{100} =  109.08


And so on: after three years we have


109.08 \cdot \frac{67}{100} = 73.08


So, the answer is somewhere between three and four years.

UkoKoshka [18]
Percent error = (estimate - real)/(real) * 100

percent error = (78.25 - 75.50)/(75.50) * 100

percent error = 3.6%

The oblique pyramid has a square base. What is the volume of the pyramid? 2.5 cm3 5 cm3 6 cm3 7.5 cm3
Olenka [21]

Take a look at the attachment below. It fills in for the attachment that wasn't provided in the question -

An oblique pyramid is one that has a top not aligned with the base. Due to this, the height of the pyramid connects with two vertices at its ends to form a right angle present outside the pyramid, knowing that it is always perpendicular to the base. There is no difference between the calculations of the volume of an oblique pyramid and a pyramid however -

\\Base Area = 2 cm * 2 cm = 4 cm^2,\\Volume ( Pyramid ) = 1 / 3 * ( Base Area ) * ( Height ),\\Volume = 1 / 3 * ( 4 ) * ( 3.75 ),\\-------------------------\\Volume = 5 cm^3

<u><em>And thus, you're solution is 5 cm^3, or in other words option b!</em></u>
