Question

75% of a number minus 7 is at most 23.

Answer 1

Given:

75% of a number minus 7 is at most 23.​

Let the number is x

so,

75% of x - 7 is at most 23

so, this inequality will be as following:

`75\%\cdot x-7\le23`

then solve the inequality to find x:

`\begin{gathered} 0.75\cdot x-7\le23 \\ 0.75x\le23+7 \\ 0.75x\le30 \\ \\ x\le(30)/(0.75) \\ \\ x\le40 \end{gathered}`
