Answer:
$117,000
Step-by-step explanation:
-0% 2004
-7% 2005
-14% 2006
-21% 2007
-28% 2008
-35% 2009
180,000 x 0.35 (35%) = 63,000
180,000 - 63,000 = 117,000
$117,000
Answer:
62
Step-by-step explanation:
well, we start by expressing the number:
a b
we understand that using the above expression, the value of the number is 10a + b
using the information in the question,
a = 3b (1)
and,
11b + 11a = 88 (2) (derived using 10a + b form)
hence, when substituting (1) into (2):
11b + 33b = 88
44b = 88
b = 2 (3)
sub (3) into (1)
a = 6
hence, the number is 62
