<h3>After 6 weeks from now you will have $190 in your bank account</h3>
<em><u>Solution:</u></em>
Given that,
You have $55 in your bank account
Each week you deposit $8 from your allowance and $15 from your paycheck
<em><u>The equation that gives the amount b in your account after w weeks is:</u></em>
b = 55 + (15 + 8)w
<em><u>How many weeks from now will you have $190 in your bank account ?</u></em>
b = 190
w = ?
Therefore,
190 = 55 + (15 + 8) w
190 = 55 + 23w
23w = 190 - 55
23w = 135
Divide both sides by 23
Thus after 6 weeks from now you will have $190 in your bank account
Incomplete Question (See Complete Question Below)
A bag contains 10 red marbles and 15 green marbles.If Yuki selects a marble from the bag without looking, what is the probability that she will pull a red marble?
A-1/5
B-2/5
C-1/2
Answer:
The probability of pulling a red marble is
Step-by-step explanation:
Given
Red Marble = 10
Green Marble = 15
Required
The probability of picking a red marble
First, the total number of marble has to be calculated
Total = Red Marble + Green Marble
Total = 10 marbles + 15 marbles
Total = 25 marbles
The probability of an event is often calculated by dividing the number of required outcomes by the number of possible outcomes.
In this case, the probability of pulling a red marble is calculated as follows:
Where P(R) represents probability of pulling a red marble
n(R) represents number of red marbles
n(R) = 10
T represents total number of marbles
T = 25
By substitution,
becomes
Reduce fraction to lowest term by dividing the numerator and denominator by 5
Hence, the probability of pulling a red marble is
