Bob and marie like to go to a good steakhouse. dinners are $14 to $16 dollars with soup or salad. a beverage is $1.25. dessert is $4.25. if one dinner is $14, the other is $16 and each diner has a beverage and dessert, what will the cost be if a 7% tax is charged and a 15% tip on the pre-tax amount is left?

$ 50.02

Step-by-step explanation:

Given,

The cost of dinners are $ 14 and $ 16,

So, the original cost of dinner = 14 + 16 = $ 30,

Now, beverage costs $1.25 each and Dessert costs $4.25 each,

Thus, the total cost of beverage and dessert for a person = $1.25 + $4.25 = $ 5.5,

∴ the total cost beverage and dessert for 2 persons = 2 × 5.5 = $ 11,

Hence, the total cost of dinner including beverage and dessert = 30 + 11 = $ 41,

Now, there is 15% tip on the pre-tax amount is left,

I.e. the amount of tip = 15% of 41 = = $6.15,

Also, there is a tax of 7%,

I.e. the amount of tax = 7% of 41 = = $ 2.87

Therefore, the total cost of the dinner = total cost of dinner including beverage and dessert + tip + tax

= 41 + 6.15 + 2.87

= $ 50.02

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.
