Priya pours the same amount of orange juice every time she fills a glass. Each glass she pours contains 21 grams of sugar. 1. Write an equation that represents how many grams of sugar \( (\mathrm{s}) \) are in some number of glasses of orange juice \( (\mathrm{g}) \). 2. How much sugar is in 4 glasses of orange juice? grams

The equation that represents how many grams of sugar \( (\mathrm{s}) \) are in some number of glasses of orange juice \( (\mathrm{g}) \) is given by: \[ \mathrm{s} = 21g \] To find out how much sugar is in 4 glasses of orange juice, you can substitute \( g \) with 4 in the equation: \[ \mathrm{s} = 21 \times 4 = 84 \] Thus, there are 84 grams of sugar in 4 glasses of orange juice.
