a group of 3 friends shared the cost of a tape recorder. if andy, barbara, and donna each paid $12, $30 and $18, respectively, then donna paid what percent of the cost of the tape recorder?
12 + 30 + 18 = 60
Donna pays $18 out of $60
= 18/60
simplify to 3/10
3/10 = 30%
Donna pays 30% of the total cost.
Well, let's do some math calculations to find out.
The total cost of the tape recorder is $12 + $30 + $18 = $60.
To figure out the percentage, we need to find out what portion of the total cost Donna paid. So, Donna's payment of $18 is a fraction of the total cost, which is $18/$60.
Now, to find the percentage, we multiply this fraction by 100: ($18/$60) * 100 = 30%.
So, Donna paid 30% of the cost of the tape recorder. She really should get some applause for shouldering a third of the burden! 🎉
To find the percentage of the cost of the tape recorder that Donna paid, we need to determine the total cost of the tape recorder first.
Given that Andy paid $12, Barbara paid $30, and Donna paid $18, we can add these amounts together to find the total cost:
$12 + $30 + $18 = $60
So, the total cost of the tape recorder is $60.
To find the percentage Donna paid, we need to calculate what portion $18 is of $60 and express it as a percentage:
($18 / $60) x 100 = 30%
Therefore, Donna paid 30% of the cost of the tape recorder.
To find out what percentage of the cost of the tape recorder Donna paid, we need to compare her payment to the total cost of the tape recorder.
Step 1: Find the total cost
To find the total cost, add up the amounts paid by each person:
Total Cost = Andy's payment + Barbara's payment + Donna's payment
Total Cost = $12 + $30 + $18
Total Cost = $60
Step 2: Calculate Donna's payment as a percentage of the total cost
Donna's payment as a percentage of the total cost can be found using the formula:
Percentage = (Donna's payment / Total Cost) * 100
Applying this formula:
Percentage = ($18 / $60) * 100
Percentage = (0.3) * 100
Percentage = 30%
Therefore, Donna paid 30% of the cost of the tape recorder.
