Final answer:
To find the total cost including sales tax, calculate the individual costs of the items and add them together. Then, calculate the sales tax by multiplying the total cost by the tax rate. Finally, add the total cost and the sales tax to find the total cost including tax.
Step-by-step explanation:
To find the total cost including sales tax, we need to first calculate the total cost of the items purchased.
The cost of cereal is $4.25, the loaf of bread is $0.75, and the 2 apples are $3.12. Adding these costs together, we get $4.25 + $0.75 + $3.12 = $8.12.
Next, we need to calculate the sales tax. The tax rate is 6%, which means we multiply the total cost by 0.06. So, $8.12 x 0.06 = $0.49.
Finally, to find the total cost including tax, we add the total cost and the sales tax. $8.12 + $0.49 = $8.61.
