Step-by-step explanation: Sorry thats all i got but good luck!
So we are given that he ordered a $15 meal
now we need to find how much will he have to pay with tax and tip
so first we find the sales tax of the meal
5% * 15 = 3/4 or 0.75
and the tip
15% * 15 = 9/4 or 2.25
we will add that to the meal price to find the total
15 + 2.25 + 0.75
total is 18
So <span>If Allam ordered a $15 meal, we will have to pay $18 with tax and tip
</span>
Hope this helps :)
