The decrease is 25% so this means that 22 is 75% of the original number (100% - 25% = 75%)
Divide 22 by 75%:
22/ 0.75 = 29.3
The answer is 29.3
Area of a circle is πr^2.
From this, we can calculate
π*2.5^2
= π*6.25
= 19.625
= 19.6
has characteristic equation
which has roots at
. The negative root has multiplicity 2. So the general solution is
Rileyflipflop,
= 8
, since she can't buy half a CD, she's limited to no more than 8 CDs. If x = the cost of one CD, then x CDs cost $18x. Since we are limited to $153, our equation looks like... 18x < 153x < 8
Again, since we can't buy half a CD, your answer should actually be... x ≤ 8 since we can buy 8 CDs or fewer.
