The answer is D, or 168.
The cheese can be any one out of 3 = 3 choices. For each of those . . .
The first topping can be any one of 8. For each of those . . .
The second topping can be any one of the remaining 7 . For each of those . . .
The third topping can be any one of the remaining 6 .

Total number of ways to assemble a pizza = (3 x 8 x 7 x 6) = 1,008 ways.

BUT . . . 

You could choose the SAME 3 toppings in (3 x 2) = 6 different ways, and
nobody could tell the difference once they were selected. All 6 different
ways would result in the same pizza.

So, out of the 1,008 total different ways there are of choosing ingredients,
there are only ( 1,008 / 6 ) = 168 different and distinct pizzas.

Help me Plz I’m stuck

spin [16.1K]

Answer:

Use all the given information:

Price of a slice in $ - x

Number of slices- 3

Total cost of slices- 3x

Price of chopped cheese in $-  2+x

Number of chopped cheeses- 4

Total cost of chopped cheeses- 8+4x

Total cost- 7x+8

Step-by-step explanation:

We are told that the price of a slice is x and that Dashaun bought 3 slices.

So to find the total amount paid for slices, multiply the price by the number of slices:

$3*x=3x$

We are told that the price of chopped cheese is $2 more than a slice. Use y as the cost for chopped cheese:

$y=2+x$

Dashaun bought 4 chopped cheeses.

To find the total cost of chopped cheeses bought, multiply the cost per cheese by the amount of cheese purchased:

$4y$

Insert the value of y:

$4(2+x)$

Use the distributive property:

$8+4x$

This is the total cost for the chopped cheeses.

To find the total of lunch, add the prices for the slices and cheeses together:

$T=3x+8+4x\\\\T=7x+8$

The total cost for lunch is 7x+8
