Work Step by Step

We start with the given equation: $1.12+1.25g=8.62$ We multiply the whole equation by $100$: $100(1.12+1.25g=8.62)$ We apply the distributive property to multiply each term by $100$: $112+125g=862$ We subtract $112$ from each side of the equation: $125g+112-112=862-112$ We combine the like terms on each side of the equation: $125g=750$ Finally, we divide by $125$ on each side of the equation: $g=\frac{750}{125}=6$
