Final answer:
Elijah paid $0.35 for tax.
Step-by-step explanation:
To find the amount Elijah paid for tax, you need to multiply the amount he spent on notebooks by the tax rate.
In this case, Elijah spent $5 on notebooks and the tax rate is 7%.
First, convert the tax rate from a percentage to a decimal by dividing it by 100. So, 7% = 7/100 = 0.07.
Then, multiply the amount spent on notebooks by the tax rate to find the tax amount. $5 * 0.07 = $0.35.
Therefore, Elijah paid $0.35 for tax.
