You are buying balloons for a party. A small balloon cost $3. A large balloon cost $4. Write an algebraic expression for the cost of x small balloons and y large balloons. Then find the total cost for 14 small balloons and 8 large balloons.
Q1: An algebraic expression for the cost of x small balloons and y large balloons is __________.
Q1 Answer: 14x + 8y
Q2: The total cost for 14 small balloons and 8 large balloons is _______.
Q2 Answer: $74
for #1, I am sure you meant 3x + 4y
#2 is correct
oh instead of 14x + 8y, i should be switch around to 3x + 4y, now I get it. thank you :)
To write the algebraic expression for the cost of x small balloons and y large balloons, we need to determine the cost of each type of balloon and combine them. Since each small balloon costs $3 and each large balloon costs $4, we multiply the number of small balloons, x, by $3 and the number of large balloons, y, by $4. The expression becomes:
Cost of x small balloons = 3x
Cost of y large balloons = 4y
Combining these expressions, we get:
Total cost = 3x + 4y
To find the total cost for 14 small balloons and 8 large balloons, we substitute x = 14 and y = 8 into the expression:
Total cost = 3(14) + 4(8)
= 42 + 32
= 74
Therefore, the total cost for 14 small balloons and 8 large balloons is $74.
I think the answer to Q1 is simply x + y
The curse of not having used a less common name.
Ty I am not sure what you mean by swapping.
Q1 asked for the algebraic expression which is x + y
Q2 has actual amounts of balloons so now these should be added to the original formula
14x + 8y where x = $3 and y = $4
Therefore
14*3 + 8*4 = $74
