Answer:

A furniture manufacturing company aims to upgrade its paint and drying section. A technical consultant suggests two investment options. The first involves purchasing Alpha brand painting and drying equipment for $8,700,000, incurring an annual maintenance fee of $2,200,000 and having a salvage value of $2,400,000 after six years. The second option is to acquire Beta brand equipment at a purchase cost of $6,800,000, with maintenance expenses starting at $900,000 in the first year and increasing by $350,000 each subsequent year. This equipment has a nine-year lifespan, with a salvage worth of $1,500,000 at the end. The minimum attractive rate of return (TMAR) is 8% per year. To make the most economical choice, considering both options yield similar productivity and income, which option should be chosen?

Explanation:

To fill in the gaps, we must first outline the entire pattern. Hence:

FIRST.

50, 150, 250,...,1050

The interval between numbers is one hundred which translates to cien

Therefore, the complete series is:

50, 150, 250, 350, 450, 550, 650, 750, 850, 950, 1050

In Spanish, this can be represented as:

Cincuenta (50), Ciento cincuenta (150), Doscientos cincuenta (250), Trescientos cincuenta (350), Cuatrocientos cincuenta (450), Quinientos cincuenta (550), Seiscientos cincuenta (650), Setecientos cincuenta (750), Ochocientos cincuenta (850), Novecientos cincuenta (950), Mil cincuenta (1050)

SECOND.

5.000, 20.000, 35.000,...,95.000

In this case, the sequence progresses by fifteen thousand which in Spanish is quince mil

Thus, the entire pattern is:

5.000, 20.000, 35.000, 50.000, 65.000, 80.000, 95.000

The Spanish representation is:

Cinco mil (5.000), Veinte mil (20.000), Treinta y cinco mil (35.000), Cincuenta mil (50.000), Sesenta y cinco mil (65.000), Ochenta mil (80.000), Noventa y cinco mil (95.000)

THIRD.

100.000, 200.000, 300.000,...,1.000.000

In this instance, the numbers are increasing by hundred thousand which translates as cien mil

Consequently, listing the full sequence yields:

100.000, 200.000, 300.000, 400.000, 500.000, 600.000, 700.000, 800.000, 900.000, 1.000.000

In Spanish, it is expressed as:

Cien mil (100.000), Doscientos mil (200.000), Trescientos mil (300.000), Cuatrocientos mil (400.000), Quinientos mil (500.000), Seiscientos mil (600.000), Setecientos mil (700.000), Ochocientos mil (800.000), Novecientos mil (900.000), Un millón (1.000.000)

FOURTH.

100.000.000, 90.000.000, 80.000.000,...,0

Here, the series is decreasing by ten million which translates to cien millones in Spanish.

So, writing out the full series gives us:

100.000.000, 90.000.000, 80.000.000, 70.000.000, 60.000.000, 50.000.000, 40.000.000, 30.000.000, 20.000.000, 10.000.000, 0

This can be articulated in Spanish as follows:

Cien millones (100.000.000), Noventa millones (90.000.000), Ochenta millones (80.000.000), Setenta millones (70.000.000), Sesenta millones (60.000.000), Cincuenta millones (50.000.000), Cuarenta millones (40.000.000), Treinta millones (30.000.000), Veinte millones (20.000.000), Diez millones (10.000.000), Cero (0)
