Julian walked 6/10 of a mile to his friends house and another 35/100 mile to the store. He walked 1/4 of a mile back home. Julia

AveGali [126]

The statement, "Julian's sister said he walked 1/5 mile" cannot be agreed because Julian totally walked $1\frac{1}{5} \text{ or } \frac{6}{5}$ miles.

<u>Solution:</u>

Given that,

Julian walked 6/10 of a mile to his friends house
Another 35/100 mile to the store
He walked 1/4 of a mile back home

To find total distance walked by Julian we have to add the above stated values. That is, $\frac{6}{10} +\frac{35}{100} +\frac{1}{4}$

Factors of 10 = $5\times2$

Factors of 100 = $5\times2\times5\times2$

Factors of 4 = $2\times2$

Therefore, the least common factor of 10, 100 and 4 is 100. With like denominators we can operate on just the numerators,

$\frac{6\times10}{10\times10} +\frac{35\times1}{100\times1} +\frac{1\times25}{4\times1}\rightarrow\frac{60+35+25}{100}\rightarrow\frac{120}{100}$

$\Rightarrow\frac{120}{100}\rightarrow\frac{6}{5}$

Which can also be written as $1\frac{1}{5}$ .

So, from the above calculation it can be said that Julian walked $1\frac{1}{5} \text{ miles }$ .

Jolene invests her savings in two bank accounts, one paying 4 percent and the other paying 10 percent simple interest per year.

Nostrana [21]

Answer:

<h2>$ 22200 in higher yielding bank and $ 44400 in lower yielding bank</h2>

Step-by-step explanation:

Jolene invests in two bank accounts. The first account gives a 4% interest per year and the second bank gives a 10% interest rate per year.

She puts twice as much in the lower yielding bank account. Let us denote the amount put in high yielding bank account by $x$ . Lower yielding bank account will have $2x$ .

$Interest\text{ }per\text{ }year=Principal\times Interest\text{ }rate$

Interest from lower yielding bank = $\dfrac{4}{100} \times 2x=\dfrac{8x}{100}$

Interest from higher yielding bank = $\dfrac{10}{100} \times x=\dfrac{10x}{100}$

Total Interest per year = $ 3996 = $\dfrac{8x}{100} +\dfrac{10x}{100}=\dfrac{18x}{100}$

$x=22200 \$$

∴ Jolene invested $ 22200 in higher yielding bank and $ 44400 in lower yielding bank.
