Question

The sum of 7 and 75% of a number is more than 23.

Answer 1

Using the variable x to represent the unknown number and knowing that 75% is equivalent to the decimal number 0.75, we can write the following inequation:

$7+0.75x>23$

Then, solving the inequation for x, we have:

$\begin{gathered} 0.75x>23-7 \\ 0.75x>16 \\ x>\frac{16}{0.75} \\ x>21.333 \end{gathered}$
