Answer:$173.90Step-by-step explanation:The most obvious way to answer this question is to multiply $9.40 by 18.5This would result in 173.90.But I realize nobody like to deal with decimals in a multiplication problem, so here's the way I would do it (especially if you don't have a calculator!)The strategy is to break it down!Multiply $9.40 x 18 hours to start, since this is easier.[tex]9.4 x 18 = 169.2[/tex]So, that's $169.20 for 18 hours of work.We aren't finished, because Abdel worked for 18.5 hours.So, what half of $9.40?[tex]9.4 / 2[/tex]= 4.7-or-$4.70So, knowing that Abdel makes $4.70 in half an hour, lets just add that onto the $169.20 we got earlier.169.2 + 4.7 = 173.9-or-$173.90 for 18.5 hours of work!
