Hi , the answer is C because 6 times 7 equals 42 , 6 times 5 equals 30 and 42 plus 30 equals 72 .

Well lets see A, B and D are too large in the parenthesis that the numbers outside of the parenthesis will use to multiply considering 42 + 30.
6(7 + 5)
6(12)
72

Answer:

$Cost\ of\ 153\ training\ sessions\ =\$4685.9\approx\$4686$

Step-by-step explanation:

$Cost\ of\ 67\ training\ sessions\ =\$2052\\\\Cost\ of\ 1\ training\ sessions\ =\frac{Total\ cost}{Total\ training\ sessions}\\\\Cost\ of\ 1\ training\ sessions\ =\frac{2052}{67}\\\\Cost\ of\ 153\ training\ sessions\ =153\times cost\ of\ 1\ training\ sessions\ \\\\Cost\ of\ 153\ training\ sessions\ =153\times\frac{2052}{67}=4685.9\\\\Cost\ of\ 153\ training\ sessions\ \$4685.9\approx4686$
