Let h be the cost of the hat before tax.
So the total value of the hat and shoes before tax is h+40.
To express the addition 8% of sales tax, taken on top of the hat and shoes, it would be 1.08 * (h+40). Note - 8% converted to a decimal is 0.08.
You are given the value 59.40 for this after tax amount.
So the final equation would be 1.08(h+40)= 59.40.
