Ken earns $20 per hour landscaping a yard. he pays $1.50 in bus fare each way. how many hours must he work to save $117? 4 hours 5 hours 3 hours 6 hours

We can solve this simply by multiplying 20 by each number (4, 5, 3, 6)

$20 X 4= $80 $80 - $1.50 - $1.50= $77. Does that make $117? No, so we move on

$20 X 5= $100 (now if you want a short cut, there's your answer right there. You can stop doing the work because automatically, $100 is lower than $117 and we know that number can only go lower, not higher)

So the answer is 6 hours

$20 X 6= $120$120 - $1.50 - $1.50 = $117.00

see below

step-by-step explanation:

x+2> 6

subtract 2 from each side

x+2-2 > 6-2

x > 4

there is an open circle at 4 since is it is greater than and the line goes to the right
