Question

Matthew filled two 20 oz. water bottles before he left home. At the end of the day, he has less than 8 oz. left. Write an inequality to determine how much water, z, Matthew drank.

Answer 1

Given data:

The expression for the inequality is,

`\begin{gathered} 2(20)-z<8 \\ 40-z<8 \end{gathered}`

Thus, the second inequality is correct.
