38%. 100 divided by 1,450 is 0.068965517241379 meaning each dollar is worth that much percentage-wise. So 0.068965517241379 times 899 for the new price would be 62% of the original price. 100%- 62% = 38%
Answer:
53
Step-by-step explanation:
M= slope = y2 - y1 / x2 - x1
(x1 , y1) = (1 , 0)
(x2 , y2) = (3 , 8)
-------------------------------------------------
m= 8 - 0/ 3 - 1
m= 4
