Final answer:
To find the tax amount, divide the total cost by the number of packages and multiply it by the tax rate.
Step-by-step explanation:
To find the amount of sales tax the school will pay for the boxes, we need to find the total cost of the boxes and then calculate the tax amount. Since the school is buying 20 packages of expo markers, we need to find the cost of one package. Given that the school is spending $100 for all 20 packages, we can divide the total cost by the number of packages:
Total cost = $100 ÷ 20 = $5
Now we can calculate the sales tax amount by multiplying the total cost by the tax rate, which is 5%:
Sales tax = $5 × 0.05 = $0.25
Therefore, the school will pay $0.25 in taxes for the boxes.
