1) a. 15% decrease
2) a. $79.20
3) b. 14.3% increase
4) a. $4.68

#1 explanation:
1435 - 1220 = 215
215/1435 = 0.1498
0.1498 x 100 = 14.98 = 15%

#2 explanation:
220 x 0.6 = 132
220-132=88
88 x 0.1 = 8.8
88-8.8 = 79.2 $

#3 explanation:
32-28=4
4/28=0.1428
0.1428 x 100 = 14.28 = 14.3%

#4 explanation:
275 x 0.15 = 41.25
275-41.25 = 233.75
233.75 x 0.02 = 4.675 = 4.68 $
