To calculate the sales tax Jim needs to pay, first, we need to find the total cost of the shoes and laces:
- Cost of shoes: $50
- Cost of laces: $1
Total cost = Cost of shoes + Cost of laces
Total cost = $50 + $1 = $51
Next, we calculate the sales tax:
Sales tax rate = 7% = 0.07
Sales tax = Total cost × Sales tax rate
Sales tax = $51 × 0.07 = $3.57
Therefore, Jim must pay $3.57 in sales tax.
