-4(3 - 2x) + 2x = 2x4
topjm [15]

Answer:

x = 2

Step-by-step explanation:

-4(3 - 2x) + 2x = 2 x 4

-12 + 8x + 2x = 2 x 4

-12 + 8x + 2x = 8

-12 + 10x = 8

-12 + 12 + 10x = 8 + 12

Investment of $3000 at 16% simple interest for 2 years

Investment of $3000 at 5% simple interest for 20 years

Investment of $1000 at 16% simple interest for 20 years

Solution:

(1) Investment of $3000 at 5% simple interest for 20 years

$\text{Simple interest}=\frac{PRT}{100}

                        $=\frac{3000\times5\times20}{100}

                        $=3000

Simple interest 1 = $3000

(2) Investment of $3000 at 16% simple interest for 2 years

$\text{Simple interest}=\frac{PRT}{100}

                        $=\frac{3000\times16\times2}{100}

                        $=960

Simple interest 1 = $960

(3) Investment of $1000 at 16% simple interest for 20 years

$\text{Simple interest}=\frac{PRT}{100}

                        $=\frac{1000\times16\times20}{100}

                        $=3200

Simple interest 1 = $3200

Order from least interest amount to greatest interest amount:

$960 < $3000 < $3200

Investment of $3000 at 16% simple interest for 2 years

Investment of $3000 at 5% simple interest for 20 years

Investment of $1000 at 16% simple interest for 20 years
