the bill for dinner was $150 if Romy paid in entire Bill and left 20% tip how much did Romy make pay in all
navik [9.2K]
Hello!

First, you'll need to find 20% of 150. You can do this by converting 20% into a decimal. To do so, you'll need to move the decimal place twice to the left to get 0.20. Now you'll need to multiply 150 by 0.20. Once you've done that, you should get $30. Now to find how much Romy paid in total, you'll need to add $30 to $150. 

Romy in total payed $180 for the bill

I hope this helps!

Tara buys two pairs of socks for 4.99 each and 3 t-shirts for 11.49 each. If she pays 6% sales tax what is the total amount of h
Alla [95]
First we add.

2 (4.99) + 3 (11.46) = $44.36

We were told that she has to pay 6% in tax, so all we have to do is multipy $44.36 by 0.06 and add that result to $44.36 and you will get this:

$44.36 * 0.06 = $2.66

$44.36 + $2.66 = $47.02
