Question

4) Suzy wants to go on her class trip to New York City. If Suzy earns $8 per hour babysitting, how many hours does she need to babysit in order to raise at least the $500 needed for the trip?

Answer 1

The earning of Suzy for an hour is $8.

Let x be the hours of babysitting to earn $500.

Determine the inequality for earning of Suzy.

$\begin{gathered} 8x\ge500 \\ \frac{8x}{8}\ge\frac{500}{8} \\ x\ge62.5 \end{gathered}$

So Suzy need to babysit atleast for 62.5 hours (62 hours and 30 min) in order to earn $500 for trip.
