Alex has a truck. 42% of the miles he drove last month were for work. If Alex drove 588 miles for work, how many miles did he dr
marshall27 [118]

Answer:

He drive <u>1,400 miles</u> last month all together.

So, option <u>B) 1,400</u> is the correct answer.

Step-by-step explanation:

Given:

Alex has a truck. 42% of the miles he drove last month were for work.

If Alex drove 588 miles for work.

Now, to find miles he drive last month all together.

Let the miles he drive last month all together be x.

42% of the miles he drove last month were for work.

Alex drove 588 miles for work.

Now, to get the miles he drive last month all together we put an equation:

42\%\ of\ x=588

\frac{42}{100} \times x=588

0.42\times x=588

0.42x=588

<em>Dividing both sides by 588 we get:</em>

x=1400\ miles.

Therefore, he drive 1,400 miles last month all together.

So, option B)  1,400 is the correct answer.
