To find 20% of 50, we can multiply 50 by 20% (which is equivalent to 0.2). So, 50 * 0.2 = 10. Therefore, 10 is the correct answer.

The difference in cost between 0.5 kilograms of red grapes at $4.50 per kilogram and 0.5 kilograms of green grapes at $3.00 per kilogram is $0.75. To calculate the cost difference, we can subtract the cost of the green grapes from the cost of the red grapes. $4.50 - $3.00 = $1.50. Since we are comparing 0.5 kilograms of each, we divide the result by 2. $1.50 / 2 = $0.75. Therefore, the correct answer is $0.75.

After Tara pays in the cheque for $52.60, her account balance increases to $42.76 + $52.60 = $95.36. Then, she writes cheques for $4.26, $3.59, and $27.80, which reduces her account balance by $4.26 + $3.59 + $27.80 = $35.65. Therefore, the amount of money left in her account is $95.36 - $35.65 = $59.71.

To find the answer, we first multiply 48.5 by 100, which gives us 4850. Then, we divide 4850 by 10, resulting in 485. Therefore, the correct answer is 485.

The student buys 4 files at $0.99 each, so the total cost of the files is 4 * $0.99 = $3.96. The student also buys 2 pads of file paper at $1.20 each, so the total cost of the pads is 2 * $1.20 = $2.40. The total cost of the files and pads is $3.96 + $2.40 = $6.36. The student gives $10.00, so the change he will receive is $10.00 - $6.36 = $3.64.

2/3 is closest to 67% because when we convert a fraction to a percentage, we divide the numerator by the denominator and multiply by 100. In this case, 2 divided by 3 equals 0.6667, which when multiplied by 100 gives us 66.67%. Rounding to the nearest whole number, we get 67%. Therefore, 67% is the closest percentage representation of 2/3.

The customer's bank balance is $3,836.52. When rounding to the nearest $10, we look at the digit in the ones place, which is 2. Since 2 is less than 5, we round down. Therefore, the rounded amount is $3,840.
