You are buying balloons for a pary. A small balloon cost $2. A large balloon cost $5. Write an algebraic expression for the cost of x small balloons and y large balloons. What is the answer?
2x + 5y
To write an algebraic expression for the cost of x small balloons and y large balloons, you need to determine the cost of each type of balloon individually and then combine them.
The cost of x small balloons is given by multiplying the number of small balloons (x) by the cost of each small balloon ($2). So, the cost of x small balloons is 2x.
Similarly, the cost of y large balloons is given by multiplying the number of large balloons (y) by the cost of each large balloon ($5). So, the cost of y large balloons is 5y.
Now, to find the total cost of both types of balloons, you sum up the cost of x small balloons and the cost of y large balloons. The algebraic expression for this is:
Total cost = 2x + 5y
To determine the answer, you need to know the specific values of x and y. If you provide the values of x and y, I can help you calculate the answer.
