zimovet [89]

Answer:

x = 6.86

Number of video games Fletcher has = 12.58

Step-by-step explanation:

Let

Number of video games Griffin has = x

Number of video games Tommy has = 3x

Number of video games Fletcher has = 3x - 8

Total number of video games is > 40

Griffin + Tommy + Fletcher > 40

x + 3x + (3x - 8) > 40

4x + 3x - 8 > 40

7x > 40 + 8

7x > 48

x > 48 / 7

x > 6.86

Number of video games Fletcher has = 3x - 8

= 3(6.86) - 8

= 20.58 - 8

= 12.58

Gelneren [198K]

Jordan have $286 in his account after 1 year.

<u>Solution:</u>

Given data:

Principal (P) = $275.00

Rate of interest (R) = 4%

Time (T) = 1 year

<u>Let us first calculate the simple interest.</u>

Simple Interest Formula:

$\text {S.I}=\frac{\text {PRT}}{100}

Substitute the given values in the simple interest formula.

$\text {S.I}=\frac{275\times4\times1}{100}

    =11

Simple interest = $11

<u>Calculating the amount in account after 1 year:</u>

Amount = Principle + Simple Interest

             = $275.00 + $11

Amount = $286

Hence Jordan have $286 in his account after 1 year.
