$g=4.27$

We start with the given equation: $25.24=5g+3.89$ We multiply the whole equation by $100$: $100(25.24=5g+3.89)$ We apply the distributive property to multiply each term by $100$: $2524=500g+389$ We subtract $389$ from each side of the equation: $2524-389=500g$ We combine the like terms on each side of the equation: $2135=500g$ Finally, we divide by $500$ on each side of the equation: $g=\frac{2135}{500}=4.27$
