Answer:
52 - 48 = 4
Around 7%
(Please tell me if this is wrong)
Answer:
<u>After a 75% increase, it would become</u>
x + 75%x = x + 0.75x = x(1 + 0.75) = 1.75x
<u>After a 50% decrease, it would become</u>
1.75x - 50%(1.75x) = 1.75x - 0.5(1.75x) = 1.75x - 0.875x = 0.875x = 
Because
is less than x, the new amount would be less than the original.
X,y is 5(5y,-2y) and 5(y-2)
