adelina 88 [10]

Answer: $1,835.00

Step-by-step explanation:

1. You know that he makes 5% of his sales plus $250 each week. He is paid $35 for each holidays and this month there are four weeks and one holiday. So, if Fernando has $4,000 in sales each week you can write the following expression:

$y=4(0.05x+250)+35$

Where y is his paid of this month and x is his sales in each week

2. Substitute x=4,000

$y=4(0.5*4,000+250)+35=1,835$

A jar contains five red marbles and three green marbles. A marble is drawn at random and not replaced. A second marble is then d

g100num [7]

Probablility that that first marble is red:
$P_{red} = \frac{red}{total}$
$P_{red} = \frac{5}{5+3}$

Probability that the second marble is green:
$P_{green} = \frac{green}{total(new)}$
$P_{green}= \frac{3}{4+3}$ (because 1 red is now gone)

$P_{total}=P_{red} \times P_{green}$
$P_{total}= \frac{6}{8} \times \frac{3}{7} = \frac{18}{56} = \frac{9}{28} \approx 32.1\%$
