Drinks at the fair cost $2.50. Use a table and an equation to represent the relationship between the numbers of drinks bought and the cost.(4 points)
Number of Drinks (x) | Cost (y)
---------------------------------------
1 | $2.50
2 | $5.00
3 | $7.50
4 | $10.00
5 | $12.50
The equation representing the relationship between the numbers of drinks bought (x) and the cost (y) is:
y = 2.50x
To represent the relationship between the number of drinks bought and the cost using a table, we can consider different values for the number of drinks and calculate the corresponding cost.
Table:
Number of Drinks (x) | Cost (y)
---------------------------------
0 | $0.00
1 | $2.50
2 | $5.00
3 | $7.50
4 | $10.00
... | ...
To represent the relationship using an equation, we can let "x" represent the number of drinks bought and "y" represent the cost. Since each drink costs $2.50, we can write the equation:
y = 2.50x
This equation shows that the cost (y) is equal to 2.50 times the number of drinks (x).
To represent the relationship between the number of drinks bought and the cost, we can use a table and an equation.
Table:
Number of Drinks (x) Cost (y)
0 $0.00
1 $2.50
2 $5.00
3 $7.50
...
Equation:
Let's assume 'x' represents the number of drinks bought, and 'y' represents the cost.
From the table, we can observe that the cost of drinks is increasing by $2.50 for each additional drink.
Therefore, the equation can be written as:
y = 2.50x
This equation represents the linear relationship between the number of drinks bought (x) and the cost (y). To find the cost (y) for a specific number of drinks bought (x), you can substitute the value of 'x' into the equation and calculate 'y'.
