Answer

Explanation:

Step1: Calculate tip for dinner

The tip is 15% of $42.00. Convert 15% to decimal: $15%=0.15$. Then $0.15\times42 = 6.3$.

Step2: Calculate total charged for MP - 3 player

The sales tax is 7% of $45.50. Convert 7% to decimal: $7% = 0.07$. The tax amount is $0.07\times45.50=3.185$. The total amount is $45.50 + 3.185=48.685\approx48.69$.

Step3: Calculate total cost of John's meal

The tip is 20% of $65.00. Convert 20% to decimal: $20%=0.2$. The tip amount is $0.2\times65 = 13$. The total cost is $65+13 = 78$.

Step4: Calculate price of suede jacket on sale

The discount is 20% of $250. Convert 20% to decimal: $20%=0.2$. The discount amount is $0.2\times250 = 50$. The price to pay is $250 - 50=200$.

Step5: Calculate price of bracelet on sale

The discount is 25% of $44. Convert 25% to decimal: $25%=0.25$. The discount amount is $0.25\times44 = 11$. The price to pay is $44 - 11 = 33$.

Answer:

  1. The tip for the dinner is $6.30.
  2. The total amount charged on the credit - card for the MP3 player is $48.69.
  3. The total cost of John's meal is $78.00.
  4. You should pay $200 for the suede jacket.
  5. The price of the bracelet on sale is $33.
