Final answer:
To find the amount the tax-exempt school group should pay for the educational software, subtract the sales tax from the bill. The group should pay $106.75.
Step-by-step explanation:
To find the amount the tax-exempt school group should pay, we need to subtract the sales tax from the bill.
First, we convert the sales tax rate of 6% to a decimal by dividing it by 100: 6% ÷ 100 = 0.06.
Then, we multiply the bill amount by the sales tax rate to find the amount of sales tax: $113.42 × 0.06 = $6.8052 (rounded to $6.81).
Finally, we subtract the sales tax from the bill amount to find the total amount the group should pay: $113.42 - $6.81 = $106.61 (rounded to $106.75).
