14.99*.12=1.80
14.99-1.8=13.19
13.19*.0625=.94
13.19+.94=14.13
final price 14.13
Number increased = 321 - 121 = 200
Percentage increased, 200/121 * 100 = 165.29%
Hope this helps!
I believe it is an acute triangle
but I also am confused on this one
Start at -150, then add 3(-5), then add 122.2. -150 + 3(-5) + 122.2 = -45.3
