Justin and his friends dan went to movie if they each bought popcorn for 4.25 and a soda for 2.25 what was their total bill after adding 5% sales tax

Add 4.25(2)+2.25(2)=13

Multiply 13*0.05 to find 5% of 13.

13*0.05=0.65, which means the 5% tax is 65 cents.

Add 0.65 and 13 to find the total bill:

0.65+13=13.65

The total bill is $13.65.

I hope this helps :)
