To calculate how much Julio spent for all the items, including tax, you need to add up the cost of the backpack, the cost of the belts, and the sales tax.
First, let's calculate the cost of the backpack and the belts. The backpack costs $39, and since Julio bought 2 belts at $17 each, the total cost of the belts is 2 x $17 = $34.
Next, let's calculate the sales tax. The sales tax is 6.5% of the total cost of all the items. To calculate this, add the cost of the backpack and belts together: $39 + $34 = $73. Now, multiply $73 by 6.5% (or 0.065) to find the sales tax amount: $73 x 0.065 = $4.745.
Finally, to find the total amount Julio spent for all the items, including tax, add the cost of the backpack, the cost of the belts, and the sales tax together: $39 + $34 + $4.745 = $77.745.
Therefore, Julio spent $77.745 for all the items, including tax.
