Answer:
4x+4y=total cost
Explanation:
We are given that there was a total of 4 bags of pretzels and 4 drinks bought. We are also given to write an expression using x dollars for the pretzels and y dollars for the drinks.
To do this, we need to multiply the cost of each pretzel bag, x, by the total amount of bags of pretzels purchased.
4·x
=4x
Next, we need to multiply the cost of each drink, y, by the total number of drinks purchased:
4·y
=4y
The question is asking us to write an expression, so put 2 and 2 together:
4x+4y=total cost
Given the actual question, "Suppose instead..." the expression would be the same.
Hope this helps! :)
