Which statement is modeled by \( 2 p+5<11 \) ? Circle the letter of the correct statement. A. The sum of 5 and 2 times \( p \) is at least 11 . B. Five added to the product of 2 and \( p \) is fewer than 11 . C. Two times \( p \) plus 5 is at most 11 . D. The product of 2 and \( p \) added to 5 is 11 .

The chemical formula for sulfuric acid is \( \mathrm{H}_{2} \mathrm{SO}_{1} \). If the chemist has 500 g of sulfuric acid, how much does the sulfur weigh? \( \left(\mathrm{H}=1_{1} \mathrm{~S}=32, \mathrm{O}=16\right) \). Round to \( 1 \mathrm{~d} . \mathrm{p} \).
