Sam is hired for a 20-day period. On days that he works, he earns $60. For each day that he does not work, $30 is subtracted fro

Alenkinab [10]

Answer:

He did not work for 6 days

Step-by-step explanation:

Sam is hired for a 20-day period.

Let x be the no. of days he did not work

So, No. of days he worked = 20-x

he earns per working day = $60

So, he earns for (20-x) days = 60(20-x)

For each day that he does not work, $30 is subtracted from his earnings.

So, Amount deducted for x days = 30x

So, His earning for 20 days = $60(20-x)-30x$

We are given that At the end of the 20-day period, he received $660

So, $60(20-x)-30x=660$

$1200-60x-30x=660$

$1200-90x=660$

$1200-660=90x$

$540=90x$

$\frac{540}{90}=x$

$6=x$

So, he did not work for 6 days

So, Option C is true

You have a standard deck of 52 playing cards and draw out a single card at random. What is the chance of picking out a nine? Wri

motikmotik

There are 9 number cards from 2 to 10 in a deck of cards.

(2-10) has one 9

There are 4 nines in a deck of 52 cards. We know that 4 x 9 = 36.

The chance or probability of taking out a 9 is (36/52).

Reducing this fraction to the lowest terms we get 9/13.
