Answer

Explanation:

Step1: Calculate the tax amount

The tax rate is (7%=0.07). The tax amount (T) on a ($18) backpack is calculated by the formula (T = 18\times0.07). [T=18\times0.07 = 1.26]

Step2: Calculate the total amount to pay

The total amount (A) to pay is the sum of the cost of the backpack and the tax. So (A=18 + T). Substitute (T = 1.26) into the formula. [A=18+1.26=19.26]

Answer:

($19.26) (the third option)
