1. What is the LCM of 4a and 10a^2?

2a
4a
20a^2
30a^2

2. Dante, a landscaper, purchased three trees.The first was $38.99.
A second was $54.99. His total bill before tax was $152.98. How
much more did he pay for the third tree than for the second one?

$93.98
$59
$16
$4.01
 
Dont know what you mean by LCM, but as for the second question:

38.99 + 54.99 + X = 152.98

X = 59.00

so, X - 54.99 = $4.01 is the answer
