Work Step by Step

We start with the given equation: $0.11k+1.50=2.49$ We multiply the whole equation by $100$: $100(0.11k+1.50=2.49)$ We apply the distributive property to multiply each term by $100$: $11k+150=249$ We subtract $150$ from each side of the equation: $11k+150-150=249-150$ We combine the like terms on each side of the equation: $11k=99$ Finally, we divide by $11$ on each side of the equation: $k=\frac{99}{11}=9$
