Hhhhmmmmm...
13.50 for food
2.40 for drink
Since there is a voucher for 1/3 of food,
13.50 multiplied by 1/3 is 4.5 which is the discount
13.50-4.5=9
9 is the final cost for the food.
Add 9 to 2.40 for the drink which results in a total of 11.40
To find the amount charged for service you multiply 11.40 by .15
11.40 × .15 = 1.71
You add 1.71 to 11.40
The total is 13.11
The standard form of an equation is

In the question, we have the following formula

To get the formula in standard form, we first have to subtract 2y from both sides (since we need to get 2y on the left side)

Finally we subtract 1 from both sides (since we need the number on the right side)

Hence, 4. is the correct answer.
