Final answer:
Sylvia's total expenditure, including the cost of cards, gifts, and a 6.25% sales tax, comes to approximately $132.81. The tax is calculated on the sum of both the cost of cards and gifts and then added to obtain the total expenditure.
Step-by-step explanation:
The question implies that Sylvia needs to calculate the total expenditure associated with her purchases, which include cards, gifts, and an additional fee or tax represented by 6.25%, though the currency for the 6.25% is not specified. To calculate this total, it is assumed that 6.25% is the sales tax rate on her total purchases.
Firstly, we calculate the total cost of her cards and gifts before tax:
- Cost of cards: $45
- Cost of gifts: $80
- Total cost before tax: $45 + $80 = $125
Next, find the sales tax:
- Convert the percentage to a decimal: 6.25% = 0.0625.
- Multiply the decimal by the total cost before tax: 0.0625 × $125 = $7.8125.
Rounding to the nearest cent, the sales tax is approximately $7.81.
Finally, add the sales tax to the total cost before tax to find the total expenditure:
Total expenditure = Total cost before tax + Sales tax
Total expenditure = $125 + $7.81 = $132.81
Therefore, Sylvia will spend a total of $132.81, including the cards, gifts, and sales tax.
