Answer:
Step-by-step explanation:
There are 24 marbles in the bag.
So,
There are 17 marbles that are either white and green.
Therefore,
"the probability of drawing a white marble" is 9/24
=0.375 or approximately as 37.5%.
Probability of drawing first white marble from the bag.
Now,
"The probability of drawing a green marble" is 8/24
=0.333 or approximately as 33.3%.
Probability of drawing a green marble.
Answer:
360
Step-by-step explanation:

Answer:
- Total cost: $3000
- Martha: $600
- Emily: $75
- Alexandra: $750
- Laura: $75
- Lisa: $1500
Step-by-step explanation:
The percentages add to 95%, so the dollar amounts (total $150) comprise 5% of the cost. Then the total cost is ...
total cost × 5% = $150
total cost = $150/0.05 = $3000
And the percentages are ...
20% × $3000 = $600 (Martha's share)
25% × $3000 = $750 (Alexandra's share)
50% × $3000 = $1500 (Lisa's share)

<em>Check</em>
$600 + 75 + 750 + 75 + 1500 = $3000 . . . as it should
