The systems of equation are .
Vanessa worked for 6 hrs and Geneva worked for 15 hrs to earn exactly $240.
Step-by-step explanation:
Let the number of hours worked by Vanessa be 'v'.
Let the number of hours worked by Geneva be 'g'.
Given:
Total number of hours worked = 21 hours
So we can say that;
Total number of hours worked is equal to sum of number of hours worked by Vanessa and number of hours worked by Geneva.
framing in equation form we get;
⇒ equation 1
Also given:
per hour earnings of Vanessa = $10
per hour earning of Geneva = $12
Total they need to earn = $240
So we can say that;
Total they need to earn would be equal to sum of per hour earnings of Vanessa multiplied by number of hours worked by Vanessa and per hour earning of Geneva multiplied by number of hours worked by Geneva.
framing in equation form we get;
⇒ equation 2
Hence The systems of equation are .
On Solving above equations we get;
First we will multiply equation 1 by 10 we get;
⇒ equation 3
Now Subtracting equation 3 from equation 2 we get;
Dividing both side by 2 we get;
Now Substituting the value of g in equation 1 we get;
Hence Vanessa worked for 6 hrs and Geneva worked for 15 hrs to earn exactly $240.
$492.50
Step-by-step explanation:
To start off, we already know that Vanessa makes at least $400 every week. What we don't know is how much Vanessa makes from her 5% commission on what she sells.
To solve for that, we need to find what 5% of $1,850 is. This can be done by multiplying $1,850 by 5%. Remember, we need to change 5% into its decimal form (5% -> -> 0.05).
$1,850 x 0.05 = $92.5
This means that Vanessa made $92.5 off of commissions last week. The last step is to add her base salary of $400 to her commission sales and we get our final answer.
$400 + $92.5 = $492.50
Vanessa's total pay last week was $492.50
$105
Step-by-step explanation:
Salary for 3 hrs=$63
Salary for 5hrs= salary for one hour×5 hrs,
Salary for one hour= 63/3=$21
Salary for 5 hours= 21×5: $105
$105
Step-by-step explanation:
I used a proportion to solve this:
Cross multiply:
3x = 315
Divide both sides by 3
x = 105
Vanessa´s total pay was $482.50.
Step-by-step explanation:
We have to add the amount of the 5% commission on Vanessa´s sales to her base salary of $400 to find out her total pay.
Since the total value of her sales was $1650, the amount (x) of her commission will be:
x = 1650 ×
x = 16.5 × 5
x = 82.50
Adding this to her base salary we get:
400 + 82.5 = 482.5
