<em>Price of a slice in $ -</em><em> x</em>
<em>Number of slices- </em><em>3</em>
<em>Total cost of slices-</em><em> 3x</em>
<em />
<em>Price of chopped cheese in $- </em><em> 2+x</em>
<em>Number of chopped cheeses-</em><em> 4</em>
<em>Total cost of chopped cheeses-</em><em> 8+4x</em>
<em />
<em>Total cost- </em><em>7x+8</em>
<em />
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:
We are told that the price of chopped cheese is $2 more than a slice. Use y as the cost for chopped cheese:
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:
Insert the value of y:
Use the distributive property:
This is the total cost for the chopped cheeses.
To find the total of lunch, add the prices for the slices and cheeses together:
The total cost for lunch is <em>7x+8</em>
