Question

An Apple store charges a fee of $25 to schedule an appointment, then $70

per hour to fix a laptop. A local tech shop charges $50 to schedule an
appointment, but only charges $65 per hour to fix a laptop. After how many
hours would the cost of fixing a laptop be the same at each store?

Answer 1

5 hrs

to work this out you need to do this:

Apple:

$70×2hrs+$25= $165

$70×3hrs+$25=$235

$70×4hrs+$25=$305

$70×5hrs+$25=$375

Local tech shop:

$65×2hr+$50=$180

$65×3hr+$50=$245

$65×4hr+$50=$310

$65×5hr+$50=$375

Now, if you go back and check both the costs you'll see that they are similar after 5 hours.
