Sagot :
The cost of one goldfish in the pet smart is $2
Let
x = cost of a goldfish
y = cost of a turtle
Elle went to pet smart and bought 4 goldfish and 4 turtles for $28. Therefore,
Elle total cost:
4x + 4y = 28
Warren went to pet smart and bought 6 goldfish and 1 turtle for $17. Therefore,
Warren total cost:
6x + y = 17
Let's combine the equation.
4x + 4y = 28
6x + y = 17
Multiply equation(ii) by 4
4x + 4y = 28
24x + 4y = 68
20x = 40
x = 40 / 20
x = 2
6(2) + y = 17
12 + y = 17
y = 17 - 12
y = 5
Therefore, the cost of one goldfish is $2.
