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\%
