Question

A web designer charges a rate of $50 per hour to design web pages. Gavin plans to hire this designer to create a website for his company. However, Gavin plans to spend no more than $350 for this service. Which inequality represents all possible values of hours, h, that Gavin can hire this designer? Oh > 7 Oh > 7 Oh < 7 Oh

Answer 1

Let h be the working hours, then we can write the following inequality

$50\cdot h\le350$

since 50 is positive, we can move it to the right hand side without change the inequalty sign, then we have

$\begin{gathered} h\le\frac{350}{50} \\ h\le7 \end{gathered}$

then, the answer is

$h\le7$
