Alright so this is pretty simple. You must add up all the costs of the breakfasts: $9.50 + $7.25 + $6.95 + $6.95 + $7.45 = $38.10. You then multiply that number by .06 and you get $ 2.286, this is the sales tax. Now since it wouldn't be logic to have .286 cents you round it to .29 cents. So, $38.10 + $2.29 will be the total cost of the bill. $40.39, final cost.
Thankkk youuu
