1. To calculate simple interest, you can use the formula: Interest = Principal x Rate x Time.
For situation a:
Principal = $2,000.00
Rate = 6% (0.06 as a decimal)
Time = 7 years
Interest = $2,000.00 x 0.06 x 7
Interest = $840.00
For situation b:
Principal = $4,500.00
Rate = 3% (0.03 as a decimal)
Time = 6 years
Interest = $4,500.00 x 0.03 x 6
Interest = $810.00
For situation c:
Principal = $1,400.00
Rate = 6% (0.06 as a decimal)
Time = 9 years
Interest = $1,400.00 x 0.06 x 9
Interest = $756.00
For situation d:
Principal = $5,000.00
Rate = 7% (0.07 as a decimal)
Time = 3 years
Interest = $5,000.00 x 0.07 x 3
Interest = $1,050.00
For situation e:
Principal = $800.00
Rate = 15% (0.15 as a decimal)
Time = 5 years
Interest = $800.00 x 0.15 x 5
Interest = $600.00
Based on the calculations, the situations with simple interest greater than $800.00 are a, b, and d.
2. To calculate the new price of the bike after a markup, you can use the formula: New Price = Original Price + (Original Price x Markup Percentage)
Original Price = $240.00
Markup Percentage = 15% (0.15 as a decimal)
New Price = $240.00 + ($240.00 x 0.15)
New Price = $240.00 + $36.00
New Price = $276.00
So, the new price of the bike is $276.00.
3. To calculate the tax, you can use the formula: Tax = Price x Tax Rate.
For pair of shoes a:
Price = $45.00
Tax Rate = 7% (0.07 as a decimal)
Tax = $45.00 x 0.07
Tax = $3.15
For pair of shoes b:
Price = $80.00
Tax Rate = 2.9% (0.029 as a decimal)
Tax = $80.00 x 0.029
Tax = $2.32
For pair of shoes c:
Price = $66.00
Tax Rate = 10% (0.1 as a decimal)
Tax = $66.00 x 0.1
Tax = $6.60
For pair of shoes d:
Price = $29.00
Tax Rate = 11% (0.11 as a decimal)
Tax = $29.00 x 0.11
Tax = $3.19
For pair of shoes e:
Price = $55.00
Tax Rate = 4.5% (0.045 as a decimal)
Tax = $55.00 x 0.045
Tax = $2.48
Based on the calculations, the pairs of shoes with tax greater than $3.00 are a, c, and d.
4. To calculate the increase in temperature, you can use the formula: Increase = Original Value x Increase Percentage.
Original Value = 50 degrees
Increase Percentage = 22% (0.22 as a decimal)
Increase = 50 degrees x 0.22
Increase = 11 degrees
The temperature on Tuesday is the original temperature plus the increase:
Temperature on Tuesday = 50 degrees + 11 degrees
Temperature on Tuesday = 61 degrees
Therefore, the temperature on Tuesday is 61 degrees.
