A store sells 12 cans of fruit cocktail for $30. What is the price of 7 cans of fruit cocktail? The price of 7 cans of fruit cocktail is
Alternatively, you could multiply $30 by (7/12).
Just use a proportion:
12 cans/7cans = $30/$x
12/7 = 30/x
12x = 210
x = 210/12 = 17.50
To find the price of 7 cans of fruit cocktail, we can use a proportion.
The given information tells us that the store sells 12 cans of fruit cocktail for $30.
So we can set up the proportion:
12 cans / $30 = 7 cans / x
To find the value of x, we cross-multiply:
12 * x = 7 * $30
Multiplying the numbers on each side gives:
12x = 210
Now, to isolate x, we divide both sides of the equation by 12:
x = 210 / 12
Simplifying the equation gives:
x = $17.50
Therefore, the price of 7 cans of fruit cocktail is $17.50.
We know that the price for 12 cans is $30. So we can set up an equation. Let c equal the price of one can.
12c=30
Now solve the equation for c, and multiply the value of c by 7.
