Answer: It is a 40 degree angle
First 10 days...average daily increase of 0.30 .....total increase for those 10 days is (0.30 x 10) = $ 3
next days.....average daily increase of 0.45....total is (0.45 x 10) = 4.50
last ten days...average daily increase of 0.25.....total is (0.25 x 10) = 2.50
it changed all together : 3 + 4.5 + 2.5 = + 10
It is showing an overall increase, so I guess u should buy it.
12% of 68 is 8.16. In order to find this answer you must change 12% into a decimal (.12) and then multiply by 68. (68×.12=8.16).
It would be false because 879 will be rounded up to 880 or 900.
