Explanation:

Step1: Let the cost be $x$.

The profit - percentage formula is $\text{Profit Percentage}=\frac{\text{Selling Price}-\text{Cost}}{\text{Cost}}\times100%$. Given that the selling price is $2$ dollars and the profit percentage is $60%$, or $0.6$ in decimal form. So we have the equation $0.6=\frac{2 - x}{x}$.

Step2: Cross - multiply.

Cross - multiplying the equation $0.6=\frac{2 - x}{x}$ gives $0.6x=2 - x$.

Step3: Add $x$ to both sides.

Adding $x$ to both sides of the equation $0.6x=2 - x$: $0.6x+x=2$, which simplifies to $1.6x = 2$.

Step4: Solve for $x$.

Dividing both sides of the equation $1.6x = 2$ by $1.6$, we get $x=\frac{2}{1.6}=\frac{20}{16}=\frac{5}{4}=1.25$.

Answer:

$1.25$
