The profit formula is the total revenue minus the total costs. Revenue is $1.35 per glass sold (1.35G), and costs are $1.27 per pound of sugar (1.27S) and $0.47 per lemon (0.47L). Therefore, the correct formula is $P = 1.35G - 1.27S - 0.47L$.

Sugar Costs $1 ρ=1.35G−1.27S−0.47L\rho = 1.35 G - 1.27 S - 0.47 Lρ=1.35G−1.27S−0.47L

Sugar Costs $1 $\rho = 1.35 G - 1.27 S - 0.47 L$
