Over the past two weeks, Jane earned $292 and $193 respectively, at her part time job. What must
she earn in the third week to bring her three-week average earnings to $200 per week?
You must earn $115
$292 +193 + 115=600
$600 divided by 3= 200
Oh Ok, I understand the question now.
Thanks a lot!
during The last winter carnival the local college students built a 30-feet snowman out of 100 tons of snow. how much snow will be needed to build a 36-foot snowman this year?
To find out how much Jane must earn in the third week to bring her three-week average earnings to $200 per week, we need to consider her earnings over the past two weeks.
First, let's calculate Jane's total earnings from the past two weeks:
Earnings in the first week: $292
Earnings in the second week: $193
To find the average, we need to calculate the total earnings over the two weeks and divide by 2:
Total earnings = $292 + $193 = $485
Average earnings over the two weeks: $485 / 2 = $242.50
Now, we know that Jane wants her three-week average earnings to be $200 per week. To find out how much she must earn in the third week, we can set up an equation:
(242.50 (average earnings over two weeks) + X (earnings in the third week)) / 3 (number of weeks) = $200
Simplifying the equation:
242.50 + X / 3 = 200
Cross-multiplying:
242.50 + X = 600
Subtracting 242.50 from both sides of the equation:
X = 600 - 242.50
X = $357.50
Therefore, Jane must earn $357.50 in the third week to bring her three-week average earnings to $200 per week.
