To solve this problem, we need to determine the value of x, which represents the number of Guppies Layla has.
Let's break down the information given:
Number of Goldfish: 2
Number of Swordtails: 3
Number of Guppies: x
Number of teaspoons of food per Goldfish: 1
Number of teaspoons of food per Swordtail: 2
Number of teaspoons of food per Guppy: 1/2
Total number of teaspoons of food: 12
We can set up the equation as follows:
(Number of Goldfish * Number of teaspoons of food per Goldfish) + (Number of Swordtails * Number of teaspoons of food per Swordtail) + (Number of Guppies * Number of teaspoons of food per Guppy) = Total number of teaspoons of food
(2 * 1) + (3 * 2) + (x * 1/2) = 12
Let's simplify and solve for x:
2 + 6 + (1/2)x = 12
To isolate x, we subtract 8 from both sides of the equation:
2 + 6 + (1/2)x - 8 = 12 - 8
(1/2)x = 4
To solve for x, we multiply both sides of the equation by 2:
2 * (1/2)x = 4 * 2
x = 8
The value of x is 8.
#### 8
The answer is: 8
