Final answer:
The total cost for the Jones family's furniture purchase and a 25% gratuity is calculated to be $906.25, which is option (c).
Step-by-step explanation:
The Jones family purchased furniture for $725 and wants to give a 25% gratuity for the delivery. To calculate the total cost including the gratuity, we first need to calculate the amount of the tip. The gratuity amount can be found by multiplying the cost of the furniture by the gratuity percentage. First, convert the percentage to a decimal by dividing it by 100, which would make the 25% gratuity 0.25 as a decimal.
Gratuity Amount = Cost of Furniture × Gratuity Percentage Decimal
Gratuity Amount = $725 × 0.25
Gratuity Amount = $181.25
The total cost including the gratuity is then the sum of the furniture cost and the gratuity amount.
Total Cost = Cost of Furniture + Gratuity Amount
Total Cost = $725 + $181.25
Total Cost = $906.25
Therefore, the total cost for the furniture and gratuity is $906.25, which corresponds to option (c).
