Word problem.
You buy 6 lb turkey
3 lb coleslaw
4 lb cheese
4 lb turkey
2 lb coleslaw
3 lb cheese.
Define and use variables to represent total cost
I got.;
6 t + 3t + 4c + 4t +2s + 3c * x
Is this right ??
I see that you are trying to define and use variables to represent the total cost of your purchases. However, there seems to be some confusion in your expression.
Let's break down the items you bought and assign variables to them:
- Turkey: You bought 6 lb initially, and then an additional 4 lb, so the total weight of turkey is 6 lb + 4 lb = 10 lb. Let's represent the cost of turkey per pound as t, so the total cost of turkey would be 10t.
- Coleslaw: You bought 3 lb initially and then 2 lb more, so the total weight of coleslaw is 3 lb + 2 lb = 5 lb. Let's represent the cost of coleslaw per pound as c, so the total cost of coleslaw would be 5c.
- Cheese: You bought 4 lb initially and then an additional 3 lb, so the total weight of cheese is 4 lb + 3 lb = 7 lb. Let's represent the cost of cheese per pound as ch, so the total cost of cheese would be 7ch.
With these variables, the expression for the total cost of your purchase would be:
Total Cost = 10t + 5c + 7ch
Note that I used "ch" to represent the cost per pound of cheese to avoid confusion with "c" which is used for coleslaw.
So, your expression should be:
6t + 3t + 4c + 4t + 2s + 3c = 19t + 7c + 2s
However, this expression doesn't account for the cheese, so the correct expression would be:
19t + 7c + 2s + 7ch.
I hope this clarifies the correct representation of the total cost using variables.
